DRV8881 Datasheet 2.5-A Dual H-Bridge Motor Driver

Manufacturer: Texas Instruments

General Description

The DRV8881 is a bipolar stepper or brushed-DC motor driver for industrial applications.

The device output stage consists of two N-channel power MOSFET H-bridge drivers.

The DRV8881 is capable of driving up to 2.5-A peak current or 1.4-A rms current per H-bridge (with proper PCB ground plane for thermal dissipation and at 24 V and TA = 25°C).
