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.

DRV10983Q: Sleep
Version
- DRV10983SQ: Standby Version
The DRV10983-Q1
device uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, which
significantly reduces the pure tone acoustics that typically occur as a result of commutation. The
interface to the device is designed to be simple and flexible. The motor can be controlled directly
through PWM, analog, or I2C inputs. Motor speed feedback is available
through both the FG pin and the I2C interface simultaneously.
The DRV10983-Q1
device features an integrated buck regulator to step down the supply voltage efficiently to 5 V for
powering both internal and external circuits. The 3.3-V LDO also may be used to provide power for
external circuits. The device is available in either a sleep mode or a standby mode version to
conserve power when the motor is not running. The standby mode (8.5 mA) version (DRV10983SQ) leaves the regulator
running and the sleep mode (48 µA) version (DRV10983Q) shuts the regulator off. Use the standby mode version in
applications where the regulator is used to power an external microcontroller. Throughout this data
sheet, the DRV10983-Q1 part
number is used for both devices for example DRV10983Q (sleep version) and DRV10983SQ (standby version), except for specific discussions of sleep vs
standby functionality.
An I2C interface allows the user to reprogram specific motor
parameters in registers and to program the EEPROM to help optimize the performance for a given
application. The DRV10983-Q1
device is available in a thermally-efficient HTSSOP, 24-pin package with an exposed thermal pad.
The operating ambient temperature is specified from –40°C to 125°C.
