3 Description

The DRV8816 provides a versatile power driver

solution with two independent ½-H bridge drivers.

The device can drive one brushed DC motor or one

winding of a stepper motor, as well as other devices

like solenoids. A simple INx/ENx interface allows

easy interfacing to controller circuits.

The output stages use N-channel power MOSFETs

configured as ½-H-bridges. The DRV8816 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 for UVLO,

charge pump fault, OCP, short-to-supply protection,

short-to-ground protection, overtemperature warning,

and overtemperature shutdown. Fault conditions are

indicated through a nFAULT pin

The DRV8816 is packaged in a 16-pin HTSSOP

package with PowerPAD™ (Eco-friendly: RoHS & no

Sb/Br)
