5 Description (Continued)
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 i.e. 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.
