3 Description  
Register setting preserved, 4.5 V to 45 V  
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.

Supports load dump voltage up to 45 V

Drive current: 2-A continuous winding current (3-A  
Peak)  
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.  
Configurable output PWM slew rate and frequency  
for EMI management  
Sensorless proprietary Back Electromotive Force  
(BEMF) control scheme (no need of hall sensors)  
•
•
Continuous sinusoidal 180° commutation  
TI provides DRV10983-Q1 tuning Guide for quick  
setup and tuning of the device for optimal
