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.
Device Options:
• DRV10983Q: Sleep Version
• DRV10983SQ: Standby Version
