Power MOSFET integrated, automotive 3-phase sensorless BLDC motor driver 'DRV10983-Q1'
The DRV10983-Q1 EVM evaluation module (EVM) is AEC-Q100 compliant. It is ideal for low-noise fans and pumps with cost constraints and a minimal number of external components. It provides a continuous current of up to 2A, saves register settings up to 4.5A, and supplies current to the motor at a supply voltage of 6.2V and below. When the supply voltage exceeds 28V, it stops motor drive to protect the DRV10983-Q1 circuitry. This feature allows it to handle load dump conditions of up to 45V. It employs a unique sensorless control method that provides continuous sinusoidal drive, significantly reducing pure tone components generated by commutation. The motor can be directly controlled via PWM, analog, or I2C inputs. Motor speed can be simultaneously fed back through the FG pin and I2C interface. Two products are available: the sleep mode version (48μA) DRV10983Q and the standby mode version (8.5mA) DRV10983SQ. The package features improved thermal characteristics in a 24-pin HTSSOP. Evaluation modules and reference designs are also available. *For more details, please contact us.*
