DRV8220 is an integrated H-bridge driver with multiple control interface options: PWM (IN1, IN2) interface (DRL and DSG packages), PH/EN (DSG only), or half-bridge interface (DSG only). To reduce area and external components on a printed circuit board, the device integrates a charge pump regulator and its capacitors. Both DSG and DRL packages support a timed auto-sleep mode which reduces microcontroller GPIO connections by eliminating a disable/sleep pin and automatically putting the device into a low-power sleep mode when the inputs remain inactive for 1-2 ms. When using autosleep for PWM or PH/EN mode, the nSLEEP pin can be tied high. The nSLEEP pin allows the device to be put to sleep in half-bridge mode where autosleep is not available.
