UA9287G-S08-R

UTC(Unisonic Tech) · Motor Driver ICs · SOP-8

UA9287G-S08-R from UTC(Unisonic Tech), 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 OUT1 output Motor output 1 of the H-bridge driver, rated for a maximum output current of 1000 mA.
2 VM power_in Motor power supply, recommended 4.5 V to 15 V.
3 VCC power_in Power supply, recommended 4.5 V to 15 V (absolute maximum 18 V).
4 FIN input Logic input (TTL compatible) that with RIN selects forward, reverse, stop or brake mode; VIH min 2.0 V, VIL max 0.8 V.
5 RIN input Logic input (TTL compatible) that with FIN selects forward, reverse, stop or brake mode; VIH min 2.0 V, VIL max 0.8 V.
6 VREF power_in Sets the HIGH level output voltage, recommended 4.5 V to 15 V.
7 OUT2 output Motor output 2 of the H-bridge driver, rated for a maximum output current of 1000 mA.
8 GND power_in Ground.
