DRV8801A-Q1 (ACTIVE) Automotive 2.8A Brushed DC Motor Driver with Current Sense (PH/EN Ctrl)

 

Special note

For evaluation purposes, please see the commercial grade evaluation module DRV8801EVM

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).

For all available packages, see the orderable addendum at the end of the datasheet.
