DRV10983PWP Datasheet PDF - TI

●The DRV10983PWP is a 3-phase sensorless brushless DC Motor Controller with integrated power MOSFETs, which can provide continuous drive current up to 2A. The device is specifically designed for cost-sensitive, low-noise/low external component count applications. The motor controller uses a proprietary sensor-less 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, analogue or I²C inputs. Motor speed feedback is available through either the FG pin or I²C. The motor controller features an integrated buck/linear regulator to efficiently step down the supply voltage to either 5 or 3.3V for powering both internal and 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.

● Sensor-less proprietary back electromotive force (BEMF) control scheme

● No external sense resistor required

● For flexibility user may include external sense

● Resistor to monitor power delivered to the motor

● Spin up profile can be customized with EEPROM

● Forward/reverse control with DIR pin

● Over-current protection

● Lock detection

● Voltage surge protection

● UVLO protection

● Thermal shutdown protection

● Green product and no Sb/Br

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
