RZ7889-MS

MSKSEMI · Brushed DC Motor Drivers · SOP-8

RZ7889-MS from MSKSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BI input Reverse (backward) logic input. VIH >= 2.2V, VIL <= 0.7V. Together with FI selects motor direction/brake/stop. Max input frequency 30 kHz; tH and tL must each be >= 100 ns.
2 FI input Forward logic input. VIH >= 2.2V, VIL <= 0.7V. Together with BI selects motor direction/brake/stop. Max input frequency 30 kHz.
3 GND power_in Device ground reference. All voltages referenced to this pin.
4 VCC power_in Power supply input. Operating range 3.0V-18V (absolute max 20V). Bypass with 470uF bulk and 0.1uF ceramic close to the pin. UVLO typ 2.2V.
5 FO output Forward H-bridge output (one of two paralleled pins for higher current). Connects to one motor terminal. Continuous output up to 5.0A; OCP typ 12A. Pins 5 and 6 must be tied together on the PCB.
6 FO output Forward H-bridge output (paralleled with pin 5). Tie to pin 5 externally.
7 BO output Reverse (backward) H-bridge output (paralleled with pin 8). Tie to pin 8 externally.
8 BO output Reverse (backward) H-bridge output (one of two paralleled pins). Connects to the other motor terminal. Continuous output up to 5.0A; OCP typ 12A.
