3 Description
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 circuits
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
PowerPAD™ package, providing enhanced thermal
dissipation.
