DRV8837CDSGR

Texas Instruments · Brushed DC Motor Drivers · WSON-8-EP(2x2)

DRV8837CDSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 VM power_in Motor power supply, 0 V to 11 V. Bypass to GND with a 0.1-µF ceramic capacitor rated for VM.
2 OUT1 output H-bridge motor output 1. Connect to one terminal of the motor winding. Peak drive current 1 A; HS+LS RDS(on) typ 1 Ω.
3 OUT2 output H-bridge motor output 2. Connect to the other terminal of the motor winding. Peak drive current 1 A; HS+LS RDS(on) typ 1 Ω.
4 GND power_in Device ground. Must be connected to the PCB ground. Tie to the exposed thermal pad (PPAD) as well.
5 IN2 input PWM bridge control input 2 (IN/IN interface). Drives OUT2. Logic-level input; VIH ≥ 0.5×VCC, VIL ≤ 0.25×VCC; internal ~100-kΩ pulldown to GND.
6 IN1 input PWM bridge control input 1 (IN/IN interface). Drives OUT1. Logic-level input; VIH ≥ 0.5×VCC, VIL ≤ 0.25×VCC; internal ~100-kΩ pulldown to GND.
7 nSLEEP input Active-low sleep mode input. Logic low puts the device in low-power sleep (IVMQ ≈ 30 nA, IVCCQ ≈ 5 nA). Logic high enables normal operation. Internal ~100-kΩ pulldown to GND; wake time ≈ 30 µs.
8 VCC power_in Logic power supply, 1.8 V to 5.5 V (abs max 7 V). Bypass to GND with a 0.1-µF ceramic capacitor rated for VCC. UVLO trips at ~1.7 V falling / 1.8 V rising.
9 PPAD passive Exposed thermal pad on package underside. Solder to the PCB ground plane for proper thermal dissipation; electrically tie to GND.
