DMOS DUAL ½-H-BRIDGE MOTOR DRIVERS

Check for Samples: DRV8816

FEATURES

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.

•

Low ON-Resistance (0.83-Ω) Outputs

Individual ½-H bridge control

Low-Power Sleep Mode

100% PWM Supported

8.0 - 38 V Operating Supply Voltage Range

Thermally Enhanced Surface Mount Package

Configurable Overcurrent Limit

Protection Features

The output stages use N-channel power MOSFET’s

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.

–

VBB Undervoltage Lockout (UVLO)

Charge Pump Undervoltage (CPUV)

Overcurrent Protection (OCP)

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.

Short-to-Supply Protection (STS)

Short-to-Ground Protection (STG)

Overtemperature Warning (OTW)

Overtemperature Shutdown (OTS)

Fault Condition Indication Pin (nFAULT)

Internal protection functions are provided for under

voltage lockout, charge pump fault, overcurrent

protection, short-to-supply protection, short-to-ground

protection,

overtemperature

warning,

and

overtemperature shutdown. Fault conditions are

indicated via an nFAULT pin

APPLICATIONS

The DRV8816 is packaged in a 16 pin HTSSOP

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

Sb/Br)
