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. |
