SA8338-MS

MSKSEMI · Brushed DC Motor Drivers · SOP-8

SA8338-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 Backward (reverse) logic input that, together with FI, selects forward, reverse, brake or stop per the truth table, must stay low or high-impedance until VCC has risen and a 3 ms delay has elapsed, and has VIH ≥ 2.2 V and VIL ≤ 0.7 V, with inputs limited to 30 kHz and tH, tL ≥ 100 ns.
2 FI input Forward logic input that, together with BI, selects forward, reverse, brake or stop per the truth table, must stay low or high-impedance until VCC has risen and a 3 ms delay has elapsed, and has VIH ≥ 2.2 V and VIL ≤ 0.7 V, with inputs limited to 30 kHz and tH, tL ≥ 100 ns.
3 GND power_in Ground reference; all voltage ratings of the device are specified with respect to this terminal.
4 VCC power_in Motor and logic power supply, operating range 3.0 V to 18 V, with an absolute maximum of 20 V, and input decoupling capacitors should be placed as close to this pin as possible.
5 FO output Forward bridge output (paired with pin 6) that is high in forward mode, low in reverse and brake modes, and open in stop mode, with continuous output current limited to 5.0 A.
6 FO output Forward bridge output (paired with pin 5) that is high in forward mode, low in reverse and brake modes, and open in stop mode, with continuous output current limited to 5.0 A.
7 BO output Reverse bridge output (paired with pin 8) that is high in reverse mode, low in forward and brake modes, and open in stop mode, with continuous output current limited to 5.0 A.
8 BO output Reverse bridge output (paired with pin 7) that is high in reverse mode, low in forward and brake modes, and open in stop mode, with continuous output current limited to 5.0 A.
