Description：

The DRV8801A-Q1 device provides a versatile motor driver solution with an H-bridge driver. This device is capable of driving a brushed DC motor or one winding of a stepper motor, as well as other loads such as solenoids. A simple PHASE and ENABLE interface easily connects to the controller circuit. The output stage uses N-channel power MOSFETs configured as an H-bridge. The DRV8801A-Q1 device can provide peak output currents of up to ±2.8A and can withstand operating voltages up to 36V. An internal charge pump is used to generate the required gate drive voltage. A low-power sleep mode shuts down parts of the internal circuitry to achieve extremely low quiescent current and power consumption. This sleep mode is controlled using a dedicated nSLEEP pin. Internal protection features include undervoltage lockout, overcurrent protection, short-to-supply protection, short-to-ground protection, overtemperature warning, and overtemperature shutdown. Overcurrent (including short-to-ground and short-to-supply) and overtemperature fault conditions are indicated by the nFAULT pin. The DRV8801A-Q1 device is available in a 16-pin WQFN package with wettable flanks and an exposed thermal pad (green: RoHS, antimony/bromine free).
