Brushed DC Motor Driver

Single H-Bridge

Datasheet (EN) 1.4

Product Overview

Key Features



Single H-Bridge Motor Driver

The device NSD7310 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.

3.6-A Peak Current Drive

PWM Control Interface

Integrated Current Chopping Regulation

Low Quiescent Sleep Mode

Small Package and Footprint

The device is integrated with current chopping regulation,

depends on VREF input and the voltage of ISEN pin, which

is proportional to current flowing through motor and an

external sense resistor. The current chopping function

limits the current during motor start-up or stall condition.

Integrated Fault Protection Features

– VM Undervoltage Protection (UV)

– Overcurrent Protection (OCP)

The device is also fully protected from faults including VM

undervoltage, overcurrent (output short to battery or short

to GND) and overtemperature. When fault condition is

removed, the device automatically resumes normal

operation.

– Over Temperature Shutdown (TSD)

– Fault with Automatically Recovery
