MCP1415T-E/OTVAO is a Microchip automotive 1.5 A low-side MOSFET gate driver in SOT-23, tape and reel — for small MOSFETs in automotive systems: load switches and small DC/DC stages. 1.5 A drive in a 3-pin SOT-23 with automotive qualification is the selection point: gate drive that fits tight automotive layouts. Selection advice: the VAO suffix denotes the automotive-qualified variant — required for automotive BOMs; for industrial designs, the standard MCP1415T-E/OT costs less. The MCP1415 differs from the MCP1416 in input polarity, so verify against the datasheet. 18 V max supply, -40 to +125 °C. Microchip lists this part as In Production. Parameters verified against the Microchip official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Selection advice: the VAO suffix denotes the automotive-qualified variant — required for automotive BOMs; for industrial designs, the standard MCP1416T-E/OT costs less. The MCP1416 differs from the MCP1415 in input polarity, so verify against the datasheet. 18 V max supply, -40 to +125 °C. Microchip lists this part as In Production.

L293D is an STMicroelectronics push-pull four-channel H-bridge motor driver with internal clamp diodes in 16-pin PowerDIP — for small DC motors, steppers and relay coils: robot kits, toys and lab fixtures. 600 mA per channel with 4.5–36 V supply is the selection point: driving motors straight from logic pins with no external diodes. Selection advice: the D suffix denotes the internal clamp diodes — the key reason to pick the L293D over the L293; for higher currents, the L298N or modern integrated drivers are the step up. Mind the ~2 V saturation drop in your motor voltage budget. Parameters verified against the ST official product page.

L6386ED013TR is an ST high-voltage high-side and low-side gate driver — SO-14, 600 V max bootstrap, 400 mA source / 650 mA sink, embedded comparator, bootstrap diode, tape and reel. The embedded comparator plus bootstrap diode is the selection point: current sensing and high-side supply in one driver — fewer external parts for 600 V half-bridge stages. Selection advice: ST lists the L6386ED013TR as Active. The ED013TR suffix pins the SO-14 package on tape and reel — match it to your footprint; the L6387 variant is the SO-8 version with fewer pins. Verify the 400 mA/650 mA drive against your MOSFET gate charge at the switching frequency. Evidence: ST data confirms Active, SO-14, 600 V bootstrap, drive currents, embedded comparator. Match the full L6386ED013TR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

L6387ED013TR is an ST high-voltage high-side and low-side gate driver — SO-8, 600 V max, 400 mA source / 650 mA sink, embedded comparator, bootstrap diode, interlocking and current-sense support, tape and reel. The SO-8 package is the selection point: 600 V half-bridge drive in an 8-pin footprint — the compact sibling of the SO-14 L6386 for space-constrained power stages. Selection advice: ST lists the L6387ED013TR as Active. The ED013TR suffix pins the SO-8 package on tape and reel — match it to your footprint; the L6386 is the larger SO-14 variant. Verify the 400 mA/650 mA drive against your MOSFET gate charge at the switching frequency. Evidence: ST data confirms Active, SO-8, 600 V, drive currents, embedded comparator. Match the full L6387ED013TR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

L6390DTR is an ST half-bridge gate driver — SO-16, 600 V high-side rail, 290 mA source / 430 mA sink, 50 V/ns dV/dt immunity, UVLO, tape and reel. The 50 V/ns dV/dt immunity is the selection point: robust half-bridge drive for fast-switching MOSFETs where high dv/dt causes false triggering in weaker drivers. Selection advice: ST lists the L6390DTR as Active. The DTR suffix denotes SO-16 on tape and reel — match it to your footprint. Verify the 290 mA/430 mA drive against your MOSFET gate charge at the switching frequency — for larger switches step up to a higher-current driver. Evidence: ST data confirms Active, SO-16, 600 V rail, drive currents, 50 V/ns immunity. Match the full L6390DTR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

L6391DTR is an ST high/low-side gate driver — SO-14, 600 V high-side rail, 290 mA source / 430 mA sink, integrated bootstrap diode, adjustable deadtime, interlocking, smart shutdown and fault-protection comparator, tape and reel. The integrated protection set is the selection point: adjustable deadtime, interlocking and smart shutdown in one driver — a protected half-bridge without external logic. Selection advice: ST lists the L6391DTR as Active. The DTR suffix denotes SO-14 on tape and reel — match it to your footprint; the L6390 is the SO-16 sibling without the full protection set. Verify the 290 mA/430 mA drive against your MOSFET gate charge at the switching frequency. Evidence: ST data confirms Active, SO-14, 600 V rail, drive currents, integrated bootstrap diode and protection features. Match the full L6391DTR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ST3485ECDR is an STMicroelectronics 3.3 V half-duplex RS-485/RS-422 transceiver in SO-8, tape and reel — guaranteed data rate of at least 12 Mbps, ±15 kV HBM / ±8 kV IEC 61000-4-2 contact ESD, standard 75176 pinout, 1 µA shutdown mode, −7 V to +12 V common-mode range, rated 0 °C to +70 °C. The 3.3 V supply with true 12 Mbps is the selection point: it runs directly from a 3.3 V MCU rail with no level translation, while older 5 V-only transceivers force an extra regulator or translator onto the board. Selection advice: the ECDR code is the commercial-temperature SO-8 reel version — the ST3485EBDR is the −40 °C to +85 °C industrial version in the same SO-8 footprint and a direct drop-in for wider ambient ranges; the ST3485ECN is the DIP-8 tube version for through-hole builds only. ST lists this code Active and shows stock on its official store; DigiKey also lists it as Active and available for ordering. Evidence: the ST official store page and ST3485 datasheet confirm the ordering code, 12 Mbps, ±15 kV ESD, SO-8 reel and Active status. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

STGAP2DMTR is an ST 1700 V isolated dual-channel gate driver — SO-16, 4 A drive, UVLO protection, galvanic isolation between gate drive signals, tape and reel. The 1700 V isolation is the selection point: dual-channel isolated drive for high-voltage SiC and IGBT stages — industrial drives and solar inverters where 600 V drivers cannot go. Selection advice: ST lists the STGAP2DMTR as Active. The DMTR suffix denotes SO-16 on tape and reel — match it to your footprint; the STGAP2SM is the single-channel narrow-body SO-8 sibling. Verify the isolation working voltage against your safety standard — 1700 V rating suits 1200 V-class power stages. Evidence: ST data confirms Active, 1700 V isolation, dual channel, SO-16, 4 A. Match the full STGAP2DMTR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

STGAP2HDMTR is an STMicroelectronics dual-channel galvanically isolated gate driver in wide-body SO-36W — 4 A sink/source per channel at 25 °C, 75 ns propagation delay, ±100 V/ns common-mode transient immunity, tape-and-reel packing (MTR), −40 to +125 °C. Galvanic isolation per the ST datasheet: 6 kV surge rating, 3500 VRMS per UL 1577, IEC 60747-17 certified. The isolated dual-channel topology is the selection point: one part drives both sides of a half bridge or full bridge while keeping the control ground fully separated from the power stage, cutting the board space and discrete isolation parts a two-chip solution needs. Separate open and close outputs plus the Miller clamp let you tune turn-on/turn-off independently, while UVLO on both supplies, thermal shutdown, SD, BRAKE and configurable interlocking with dead time simplify shoot-through-proof designs for motor drives, inverters and EV charging. Selection advice: this is the dual (D) member of the STGAP2 family — the STGAP2HSx are the single-channel wide-body SO-8W parts; pick D when one package must cover both bridge legs, and keep its pinout off-limits as a drop-in for single-channel drivers. ST lists STGAP2HDMTR as Active. Evidence: ST STGAP2HD datasheet and ST eStore confirm 4 A, 75 ns, ±100 V/ns CMTI, isolation ratings, SO-36W and tape-and-reel packing. Match the full STGAP2HDMTR code.
