NSD7310 - NOVOSENSE

NSD7310 Brushed DC Motor Driver

SYMBOL No TYPE DESCRIPTION GND 1 PWR Logic ground. Connect to board ground IN1 3 I Logic inputs 1. Controls the H-bridge output. Has internal pull downs. IN2 2 I Logic inputs 2. Controls the H-bridge output. Has internal pull downs. High-current ground path. If using current regulation, connect ISEN to a resistor (low-value, ISEN 7 PWR high-power-ratin.

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 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. 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. App.
