DRV8801A-Q1 DMOS Full-Bridge Motor Drivers

1 Features

3 Description

•

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

– V_BBUndervoltage 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)

are

provided

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.

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).
