DRV8873SPWPR

DRV8873SPWPR is a Texas Instruments 10 A peak H-bridge motor driver in 24-pin HTSSOP with PowerPAD, tape-and-reel packing (R, 2000 per reel) — 4.5 V to 38 V supply, four N-channel MOSFETs at 150 mΩ HS+LS (25 °C, 13.5 V), integrated IPROPI current-mirror feedback (no external high-power sense resistor needed), PH/EN or PWM or independent half-bridge control, logic inputs compatible with 1.8 V / 3.3 V / 5 V, 10 uA low-power sleep mode, −40 to +125 °C. The SPI interface is the selection point: current-regulation trip level (4 A / 5.4 A / 6.5 A / 8 A), PWM off-time (20–80 us), slew rate (2.6–53.2 V/us), OCP response (latched / retry) and thermal-shutdown mode are all register-configurable, and fault detail reads back through nFAULT and SPI registers instead of a bare fault flag. Selection advice: the S in DRV8873SPWPR is the SPI-control variant; DRV8873HPWPR is the pin-strap hardware-interface version — choose SPI when the firmware needs to tune current limits and diagnose faults, hardware when a driver that works with zero register writes is wanted. Match the full DRV8873SPWPR code. TI lists DRV8873SPWPR as Active. Evidence: TI DRV8873 datasheet (SLVSET1) and package addendum confirm 10 A peak, 4.5–38 V, 150 mΩ, SPI interface, HTSSOP-24 and tape-and-reel packing.
