3 Description

The DRV8802 provides an integrated motor driver

solution for printers, scanners, and other automated equipment applications. The device has two H-bridge

drivers, and is intended to drive DC motors. The

output driver block for each consists of N-channel

power MOSFET’s configured as H-bridges to drive the motor windings. The DRV8802 can supply up to

1.6-A peak or 1.1-A RMS output current (with proper

heatsinking at 24 V and 25°C) per H-bridge.

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 over

current protection, short circuit protection, under voltage lockout and overtemperature.

The DRV8802 is available in a 28-pin HTSSOP

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

Sb/Br).
