FEATURES

DESCRIPTION

The DRV8816 provides a versatile power driver

•

Low ON-Resistance (0.83-

Ω) Outputs

solution with two independent ½-H bridge drivers.

•

Individual ½-H bridge control

The device can drive one brushed DC motor or one

•

Low-Power Sleep Mode

winding of a stepper motor, as well as other devices

like solenoids. A simple INx/ENx interface allows

•

100% PWM Supported

easy interfacing to controller circuits.

•

8.0 - 38 V Operating Supply Voltage Range

The output stages use N-channel power MOSFET’s

•

Thermally Enhanced Surface Mount Package

configured as ½-H-bridges. The DRV8816 is capable

•

Configurable Overcurrent Limit

of peak output currents up to ±2.8 A and operating

•

Protection Features

voltages up to 38 V. An internal charge pump

generates needed gate drive voltages.

–

VBB Undervoltage Lockout (UVLO)

–

Charge Pump Undervoltage (CPUV)

A low-power sleep mode is provided which shuts

down internal circuitry to achieve very low quiescent
