3 Description

The DRV10983-Q1 device is a 3-phase sensorless

motor driver with integrated power MOSFETs, which

can provide continuous drive current up to 2 A. The

device is specifically designed for cost-sensitive, low-

noise, low-external-component-count fan and pump

applications.

The DRV10983-Q1 device preserves register setting

down to 4.5 V and delivers current to the motor with

supply voltage as low as 6.2 V. If the power supply

voltage is higher than 28 V, the device stops driving

the motor and protects the DRV10983-Q1 circuitry.

This function is able to handle a load dump condition

up to 45 V.

TI provides DRV10983-Q1 tuning Guide for quick

setup and tuning of the device for optimal

performance.

Device Options:

• DRV10983Q: Sleep Version

• DRV10983SQ: Standby Version
