SA8339-MS

MSKSEMI · Brushed DC Motor Drivers · SOP-8

SA8339-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-direction logic input with VIH min 2.2 V, VIL max 0.7 V, input high current 110 µA typical at 5 V, and a 18 V maximum input voltage; it should be left floating or held low/high-impedance until 3 ms after VCC power-up, and must not be driven high before then.
2 FI input Forward-direction logic input with VIH min 2.2 V, VIL max 0.7 V, input high current 110 µA typical at 5 V, and a 18 V maximum input voltage; it should be left floating or held low/high-impedance until 3 ms after VCC power-up, and input control frequency must not exceed 30 kHz.
3 GND power_in Ground terminal to which all voltages in the datasheet are referenced.
4 VCC power_in Power supply input with operating range 3.0 V to 18 V (absolute maximum 20 V), with undervoltage lockout at 1.9 V to 2.8 V, and VCC input capacitors (0.1 µF plus bulk) to be placed as close to this pin as possible.
5 FO output Forward H-bridge output, paired internally with pin 6, rated for 5.0 A continuous output current on a 40 mm² single-sided FR4 PCB (9.0 A absolute maximum), and open in stop mode.
6 FO output Forward H-bridge output, paired internally with pin 5, rated for 5.0 A continuous output current on a 40 mm² single-sided FR4 PCB (9.0 A absolute maximum), and open in stop mode.
7 BO output Reverse H-bridge output, paired internally with pin 8, rated for 5.0 A continuous output current on a 40 mm² single-sided FR4 PCB (9.0 A absolute maximum), and open in stop mode.
8 BO output Reverse H-bridge output, paired internally with pin 7, rated for 5.0 A continuous output current on a 40 mm² single-sided FR4 PCB (9.0 A absolute maximum), and open in stop mode.
