NSD7312
Overview
The device NSD7312 is a brushed-DC motor H-bridge driver for Automotive VCU/OBC charger inlet locking, and industrial market including printer, appliance, robotics or other small machines application. Two logic inputs control the H-bridge driver consisted of four N-channel MOSFETs. The device can control motors bidirectionally with up to 3.6A peak current. The input can be PWM modulated to control motor speed using current chopping method. The device enters sleep mode with low quiescent with both inputs IN1, IN2 low.
The device is integrated with current chopping regulation, based on internal reference and the voltage on the ISEN pin, which is proportional to current flowing through motor through an external sense resistor. The current chopping function limit the peak current to a known level can reduce the system power requirements and bulk capacitance required to maintain stable output voltage especially for motor startup and stall condition.
