MS7889

MSKSEMI · Brushed DC Motor Drivers · SOP-8

MS7889 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 that, together with FI, selects forward, reverse, brake or stop; the datasheet gives VIH min 2.2 V and VIL max 0.7 V and keeps BI low or high-impedance until 3 ms after VCC power-up.
2 FI input Forward-direction logic input that, together with BI, selects forward, reverse, brake or stop; the datasheet gives VIH min 2.2 V and VIL max 0.7 V and keeps FI low or high-impedance until 3 ms after VCC power-up.
3 GND power_in Ground terminal to which all voltages in the datasheet are referenced.
4 VCC power_in Motor and logic supply pin with an operating range of 3.0 V to 18 V and an absolute maximum of 20 V.
5 FO output Forward-side H-bridge output driving the motor; it is tied internally to pin 6 and is high in forward mode and low in reverse mode.
6 FO output Forward-side H-bridge output driving the motor; it is tied internally to pin 5 and is high in forward mode and low in reverse mode.
7 BO output Reverse-side H-bridge output driving the motor; it is tied internally to pin 8 and is high in reverse mode and low in forward mode.
8 BO output Reverse-side H-bridge output driving the motor; it is tied internally to pin 7 and is high in reverse mode and low in forward mode.

CAD (KiCad official)

  • Symbol: MS7889
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ms7889-etched.step / ms7889-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ms7889.step / ms7889.glb are the bare package body.
