NSD7312A
Overview
The device NSD7312A is a H-bridge driver for brushed-DC motor used for applications including printer, robotics, or other small motor actuators. With two inputs (IN1 & IN2) and the 4x integrated N-channel MOSFETs, the device can control external 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 also features sleep mode with low quiescent current when both IN1 and IN2 inputs are low.
The device is integrated with current chopping regulation, depends on the internal reference Vtrip and the voltage of IPROBE pin, which is proportional to the current output of the integrated current mirror of the current flowing through motor and IPROBE output resistor. The current chopping function limits the current during motor start-up or stall condition.
The device is also fully protected from faults including VM undervoltage, overcurrent (output short to battery or short to GND) and...
