The DRV8801-Q1 provides a versatile power driver solution with a full H-bridge driver.
The device can drive a brushed DC motor or one winding of a stepper motor, as well as other devices
like solenoids. A simple PHASE/ENABLE interface allows easy interfacing to controller
The output stages use N-channel power MOSFETs configured as ½-H-bridges. The DRV8801-Q1
is capable of peak output currents up to ±2.8 A and operating voltages up to 38 V. An internal
charge pump generates needed gate drive voltages.
A low-power sleep mode is provided which shuts down internal circuitry to achieve very
low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin.
Internal protection functions are provided: 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 via an nFAULT pin.
The DRV8801-Q1 is
packaged in a 16-pin QFN package with exposed thermal pad, providing enhanced thermal
