TPS53688

Dual-channel multiphase step-down controller (up to 8 phases: 6+2 or 5+3) with D-CAP+ control, PMBus telemetry and on-chip NVM. Covers 4.5-17 V in, 0.25-2.8125 V out at up to 300 A, switching 300 kHz-1 MHz in a 5x5 mm 40-pin WQFN. Undershoot-reduction and dynamic phase shedding cut output capacitance and hold efficiency across light and heavy loads, so AI-accelerator and FPGA core rails get tighter transient response with a smaller BOM; NVM stores the tuned configuration and trims external parts. Proven in TI reference designs for Xilinx Versal ACAP and Virtex UltraScale+ 200-A rails (PMP22165, TIDA-050020). Sourcing note: pair with TI NexFET smart power stages such as CSD95490 as in the official EVM; if a single rail must exceed about 300 A, step up to the 12-phase TPS536C7 instead of paralleling controllers. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Dual-channel D-CAP+ multiphase controller scaling to 12 phases (12+0, 11+1 or 10+2) for up to 400 A on datacenter ASIC and AI-accelerator core rails. 4.5-18 V input, 0.25-5 V output, PMBus telemetry and fault reporting, 6x6 mm 48-pin VQFN. The 12-phase interleaving spreads current and heat, letting one controller replace paralleled regulators on 360-A-class rails - TI's PMP21887 reference design demonstrates 360 A continuous / 600 A peak for datacenter hardware. Sourcing note: compared with the 8-phase TPS53681 (which adds NVM), choose TPS536C7 when the rail exceeds about 300 A or needs 12-phase granularity; the datasheet orderable is listed as TPS536C7B1, so confirm the exact suffix on your PO. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

BQ4050RSMR is a Texas Instruments battery fuel gauge — for 1-series Li-ion and Li-polymer packs: Impedance Track gauging algorithm for accurate state-of-charge reporting, integrated protection-friendly architecture, VQFN-12 package. The Impedance Track algorithm learns the cell characteristics over cycles, so reported capacity stays accurate as the battery ages — unlike simple coulomb counters that drift; accurate gauging prevents both unexpected shutdowns and over-conservative capacity margins. Business impact: reliable fuel gauging is a safety and user-experience feature — medical, industrial and consumer devices all depend on trustworthy remaining-capacity readings. Selection advice: the RSMR code denotes VQFN-12 on tape and reel — the BQ4050 targets single-cell packs — for multi-cell designs look at the BQ40 family stackable gauges; cell characterization data improves initial accuracy. Ranked #15 on the hqbuy.com real-time hot list (2026-10-05). Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Integrated temperature-compensated bidirectional current sense and analog temperature output feed the controller's telemetry loop, while 1.75 MHz switching and ultra-low-inductance packaging push power density. This is the ACTIVE successor to the NRND CSD95490 — same footprint class, higher current rating. Selection advice: pair with TI multiphase controllers (TPS53681/TPS53688 on this site) per TI reference designs; the industry-common 5x6 mm footprint allows second-sourcing across vendors, but verify current-sense calibration against your controller. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DRV8256PPWPR is a Texas Instruments single H-bridge motor driver with integrated current sense and smart-tune technology — for industrial brushed-DC drives: 4.5-V to 48-V supply, 6.4-A peak output, 165-mΩ RDS(ON), and an internal current-mirror sense architecture that removes the power shunt resistor. The selection point is the inrush control: the driver regulates motor startup current automatically, protecting 24-V and 48-V rails from stall-current collapse — plus spread-spectrum clocking for low EMI in noise-sensitive cabinets. Selection advice: the PPWPR suffix is the HTSSOP-28 tape-and-reel orderable — the E variant (DRV8256EPWPR) uses EN/IN control while the P variant uses PH/EN, so match the control interface to your MCU firmware; for the compact 4x4-mm VQFN specify the RGER variant. TI lists this as Active in production. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DRV8350 is a Texas Instruments 102-V max 3-phase smart gate driver — for BLDC motor drives in drones, robotics, e-bikes, power tools and factory automation: 9-V to 100-V triple half-bridge driver with smart gate drive architecture, adjustable slew rate for EMI control, and VGS handshake plus minimum dead-time insertion to prevent shoot-through. The selection point is the integration: optional triple low-side current shunt amplifiers and an integrated buck regulator (LM5008A-based, 6-V to 95-V in, 350-mA out) collapse the gate-drive power tree onto one chip. Selection advice: the hardware-interface variant suits cost-sensitive designs, while the SPI variant adds fault reporting and configurability — for 65-V systems the DRV8320 is the lower-voltage sibling; pair with TI NexFET power stages per the DRV8350H-EVM reference. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
