产品描述

The DRV8842 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, one coil of a stepper motor, or other loads. The output driver block consists of N-channel power MOSFET’s configured as an H-bridge. The DRV8842 can supply up to 5-A peak or 3.5-A RMS output current (with proper heatsinking at 24 V and 25°C).

Separate inputs to independently control each half of the H-bridge are provided.

Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature.

TheDRV8842 is available in a 28-pin HTSSOP package with PowerPAD (Eco-friendly: RoHS & no Sb/Br).
