TMI · Motor Driver ICs · SSOP-10

TMI8549 from TMI, in a SSOP-10. 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 VCC power_in Power-supply voltage pin (4V to 16V operating, 20V absolute max); connect a stabilization capacitor to GND.
2 ENA input Motor drive control enable input; L (0V to 0.4V) is stand-by mode with 0A current, H (1.5V to 5.5V) enables outputs, PWM can be input, built-in 100kΩ pull-down.
3 IN1 input Drive control input for OUT1 and OUT2; PWM can be input, built-in 100kΩ pull-down.
4 IN2 input Drive control input for OUT3 and OUT4; PWM can be input, built-in 100kΩ pull-down.
5 NC unconnected Not connected.
6 GND power_in Ground pin.
7 OUT4 output Driving output pin; the motor coil is connected between this pin and OUT3.
8 OUT3 output Driving output pin; the motor coil is connected between this pin and OUT4.
9 OUT2 output Driving output pin; the motor coil is connected between this pin and OUT1.
10 OUT1 output Driving output pin; the motor coil is connected between this pin and OUT2.
