TMI8110

TMI · Brushed DC Motor Drivers · ESOP-8

TMI8110 from TMI, in a ESOP-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 IN1 input Logic input that controls the H-bridge output, with an internal pulldown; logic-high input is 1.5 V to 5.5 V (VIH) and logic input voltage is rated 0 to 5.5 V.
2 IN2 input Logic input that controls the H-bridge output, with an internal pulldown; logic-high input is 1.5 V to 5.5 V (VIH) and logic input voltage is rated 0 to 5.5 V.
3 nSLP input Sleep mode input: logic high enables the device and logic low enters the low-power sleep mode, with an internal pulldown; nSLP must go high at least 3 ms after power-on.
4 VREF power_in External reference voltage input that sets the internal current regulation limit; the recommended range is 0 to 3.6 V and the absolute maximum is -0.3 to 6 V.
5 IPROPI output Analog output current proportional to the load current (1000 µA/A scaling), converted to a voltage with an external resistor RIPROPI; the recommended output current is 0 to 3 mA and the absolute maximum pin voltage is -0.3 to 6 V.
6 OUT1 output H-bridge output that connects to the motor or other load; the absolute maximum pin voltage is -0.7 V to VM+0.7 V.
7 OUT2 output H-bridge output that connects to the motor or other load; the absolute maximum pin voltage is -0.7 V to VM+0.7 V.
8 VM power_in Motor supply input from 4.5 V to 37 V (absolute maximum 40 V), which requires a 0.1 µF bypass capacitor to ground plus sufficient bulk capacitance rated for VM.
9 GND power_in Logic ground that should be connected to the board ground.
