3 Description

The DRV8840 provides an integrated motor driver

solution for printers, scanners, and other automated

equipment applications. The device has one H-bridge

driver, and is intended to drive one DC motor. The

output driver block for each consists of N-channel

power MOSFETs configured as full H-bridges to drive

the motor windings. The DRV8840 can supply up

to 5-A peak or 3.5-A output current (with proper

heatsinking at 24 V and 25°C).

A simple parallel digital control interface is compatible

with industry-standard devices. Decay mode is

programmable to allow braking or coasting of the

motor when disabled.

Internal shutdown functions are provided for

overcurrent protection, short-circuit protection,

undervoltage lockout, and overtemperature.

The DRV8840 is available in a 28-pin HTSSOP

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

Sb/Br).
