Qualified for Automotive Applications
Low ON-Resistance (0.83 Ω) Outputs
Low-Power Sleep Mode
100% PWM Duty Cycle Supported
6.5 to 36-V Operating Supply Voltage Range
Thermally Enhanced Surface-Mount Package
Configurable Overcurrent Limit
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.
Protection Features
– VBB Undervoltage Lockout (UVLO)
– Overcurrent Protection (OCP)
– Short-to-Supply Protection
– Short-to-Ground Protection
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.
– Overtemperature Warning (OTW)
– Overtemperature shutdown (OTS)
– Overcurrent and Overtemperature Fault
Conditions Indicated On Pin (nFAULT)

2 Applications
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.
