3 Description
The DRV8801A-Q1 device provides a versatile
motor-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 and ENABLE interface
allows easy interfacing to controller circuits.
The output stages use N-channel power MOSFETs
configured as an H-bridge. The DRV8801A-Q1
device is capable of peak output currents up to ±2.8
A and operating voltages up to 36 V. An internal
charge pump generates required 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 DRV8801A-Q1 device is packaged in a 16-pin
WQFN package with wettable flanks and exposed
thermal pad (Eco-friendly: RoHS & no Sb/Br).
