NSD7310A - NOVOSENSE

NSD7310A Brushed DC Motor Driver

SYMBOL No TYPE DESCRIPTION IPROBE 1 O Current feedback output pin, Put external resistor on this pin to ground. See application information section for resistor selection IN1 3 I Logic inputs. Controls the H-bridge output. Has internal pull downs. IN2 2 I Logic inputs. Controls the H-bridge output. Has internal pull downs. PGND 7 PWR High-current gro.

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 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 overtemperature. When fault condition is remove.
