DRV8838DSGR Description

For cameras, consumer items, toys, and other low-voltage or battery-powered motion control applications, the DRV8838DSGR provides an integrated motor driver solution. The gadget has the ability to control one dc motor as well as additional devices such as solenoids. To drive the motor winding, the output driver block consists of N-channel power MOSFETs organized as an H-bridge. Gate drive voltages are generated by an internal charge pump. The DRV8838DSGR has a maximum output current of 1.8 A. The motor power supply voltage ranges from 0 to 11 V, while the device power supply voltage ranges from 1.8 V to 7 V. The PWM (IN1-IN2) input interface on the DRV8838DSGR is different from the PH-EN input interface on the DRV8838 device. Both interfaces work with industry-standard hardware. Overcurrent protection, short-circuit protection, under-voltage lockout, and overtemperature protection are all built-in.
