DRV8802PWP

直流电动机驱动器IC DC MOTOR DRIVER IC

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.
