Texas Instruments  DRV10983QPWPRQ1

The DRV10983-Q1 device is a 3-phase sensorless motor driver with integrated powerMOSFETs, which can provide continuous drive current up to 2 A. The device is specifically designedfor 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 tothe motor with supply voltage as low as 6.2 V. If the power supply voltage is higher than 28 V, thedevice stops driving the motor and protects the DRV10983-Q1 circuitry. This function is able tohandle a load dump condition up to 45 V.

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

The DRV10983-Q1 device uses a proprietary sensorless control scheme to provide continuoussinusoidal drive, which significantly reduces the pure tone acoustics that typically occur as aresult of commutation. The interface to the device is designed to be simple and flexible. The motorcan be controlled directly through PWM, analog, or I2C inputs. Motorspeed feedback is available through both the FG pin and the I2Cinterface simultaneously.

The DRV10983-Q1 device features an integrated buck regulator to step down the supplyvoltage efficiently to 5 V for powering both internal and external circuits. The 3.3-V LDO also maybe used to provide power for external circuits. The device is available in either a sleep mode or astandby 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 usedto power an external microcontroller. Throughout this data sheet, the DRV10983-Q1 part number isused for both devices i.e. DRV10983Q (sleep version) and DRV10983SQ (standby version), except forspecific discussions of sleep vs standby functionality.

An I2C interface allows the user to reprogram specific motorparameters in registers and to program the EEPROM to help optimize the performance for a givenapplication. The DRV10983-Q1 device is available in a thermally-efficient HTSSOP, 24-pin packagewith an exposed thermal pad. The operating ambient temperature is specified from –40°C to125°C.
