Texas Instruments DRV8843 Dual H-Bridge Drivers
Texas Instruments DRV8843 Dual H-Bridge Drivers provide an integrated bridge motor driver solution for printers, scanners, and other automated equipment applications. These devices can drive one or two brushed DC motors, a bipolar stepper motor, or other loads. A simple PWM interface allows easy interfacing with controller circuits. The Texas Instruments DRV8843 drivers operate from 8.2V to 45V supply voltage range. Internal protection features include overtemperature, overcurrent, and under voltage. Other applications include office automation machines, gaming machines, factory automation, and robotics.Features
