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 package with exposed thermal pad,
providing enhanced thermal dissipation.
