SA8345-MS

MSKSEMI · Brushed DC Motor Drivers · SOP-8

SA8345-MS from MSKSEMI, 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 BI input Reverse (backward) logic input; with FI selects forward, reverse, brake or stop, logic high min 2.2V, low max 0.7V.
2 FI input Forward logic input; with BI selects forward, reverse, brake or stop, logic high min 2.2V, low max 0.7V, max input frequency 30kHz.
3 GND power_in Ground; all voltage values are referenced to this terminal.
4 VCC power_in Power supply for the motor driver, recommended operating range 3V to 30V (absolute maximum 33V).
5 FO output Forward H-bridge output, tied to pin 6 and driven high in forward mode (continuous output current up to 6.0A).
6 FO output Forward H-bridge output, tied to pin 5 and driven high in forward mode (continuous output current up to 6.0A).
7 BO output Backward H-bridge output, tied to pin 8 and driven high in reverse mode (continuous output current up to 6.0A).
8 BO output Backward H-bridge output, tied to pin 7 and driven high in reverse mode (continuous output current up to 6.0A).
