DRV8872DDAR

Texas Instruments · Stepper Motor Driver · HSOP-8-EP

DRV8872DDAR from Texas Instruments, in a HSOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Logic ground connecting to board ground plane.
2 IN2 input Logic input with internal pulldown controlling H-bridge output state.
3 IN1 input Logic input with internal pulldown controlling H-bridge output state.
4 nFAULT tri_state Open-drain fault status output indicating UVLO, TSD, or OCP fault; requires external pullup resistor.
5 VM power_in Power supply input voltage of 6.5 V to 45 V; requires 0.1 µF bypass capacitor and bulk capacitors rated for supply voltage.
6 OUT1 output H-bridge motor drive output connected directly to motor or inductive load.
7 ISEN power_in High-current ground path; connect to low-value sense resistor for current regulation or directly to ground.
8 OUT2 output H-bridge motor drive output connected directly to motor or inductive load.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
