TMI8230 from TMI, in a DFN-8-EP(2x2). 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 | Motor driver power supply (1.8V to 11V); connect a 0.1μF ceramic bypass capacitor and a 47μF bulk capacitor to GND. |
| 2 | OUT1 | output | H-bridge motor driver output 1. |
| 3 | OUT2 | output | H-bridge motor driver output 2. |
| 4 | GND | power_in | Ground pin. |
| 5 | IN2 | input | Control logic input 2 with internal pulldown (100kΩ typical). |
| 6 | IN1 | input | Control logic input 1 with internal pulldown (100kΩ typical). |
| 7 | EN | input | Chip enable input; logic low puts the device in low-power sleep mode, logic high gives normal operation, with an internal pulldown resistor to GND. |
| 8 | VCC | power_in | Logic input power supply (1.8V to 7V); connect a 0.1μF ceramic bypass capacitor to GND. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
