BD6221F-E2

ROHM Semicon · Motor Driver ICs · SOP-8

BD6221F-E2 from ROHM Semicon, 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 OUT1 output H-bridge driver output 1; for the BD6221 the maximum output current is 1.0 A (IOMAX, Note 2).
2 VCC power_in Motor and logic supply; recommended supply voltage is 6 V to 15 V, absolute maximum 18 V, and all VCC pins must be held at the same voltage.
3 VCC power_in Motor and logic supply; recommended supply voltage is 6 V to 15 V, absolute maximum 18 V, and all VCC pins must be held at the same voltage.
4 FIN input Forward control input; logic high requires VIH of at least 2.0 V, logic low requires VIL of at most 0.8 V, and the input frequency range is 20 kHz to 100 kHz.
5 RIN input Reverse control input; logic high requires VIH of at least 2.0 V, logic low requires VIL of at most 0.8 V, and the input frequency range is 20 kHz to 100 kHz.
6 VREF power_in Duty setting pin for PWM speed control; recommended VREF voltage is 3 V to 15 V.
7 OUT2 output H-bridge driver output 2; for the BD6221 the maximum output current is 1.0 A (IOMAX, Note 2).
8 GND power_in Ground reference; all voltages in the absolute maximum and recommended operating ratings are referenced to this pin.
