TMI8837S

TMI · Brushed DC Motor Drivers · SOP-8

TMI8837S from TMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VM power_in Power supply for the driver: connect a 0.1μF ceramic bypass capacitor to GND, and a bulk capacitor of at least 22μF on VM to GND is needed to stabilize VM during motor operation; VM range is 1.8V to 11V.
2 OUT1 output Motor driver output 1 (H-bridge output); voltage is limited to -0.3V to Vin+0.3V per the absolute maximum ratings.
3 OUT2 output Motor driver output 2 (H-bridge output); voltage is limited to -0.3V to Vin+0.3V per the absolute maximum ratings.
4 GND power_in Ground pin.
5 IN2 input PWM input 2 controlling the H-bridge; logic inputs are rated -0.3V to 7V absolute maximum, with thresholds referenced to VCC.
6 IN1 input PWM input 1 controlling the H-bridge; logic inputs are rated -0.3V to 7V absolute maximum, with thresholds referenced to VCC.
7 EN input Chip enable input: logic low puts the device into low-power sleep mode and logic high enables normal operation; it has an internal 100kΩ pull-down to GND and is rated -0.3V to 7V.
8 VCC power_in Power supply for logic inputs, 1.8V to 7V; connect a 0.1μF ceramic bypass capacitor to GND.
