Introduction

AI Translation

The DRV10975 device is a three-phase sensorless motor driver with integrated power MOSFETs, capable of providing a continuous drive current of up to 1.5A. This device is designed for cost-sensitive, low-noise applications with a low number of external components. The DRV10975 device uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, which can significantly reduce the pure tones typically generated during the commutation process. The interface of this device is designed to be simple and flexible. The motor can be directly controlled via PWM, analog, or I²C inputs. Motor speed feedback can be provided through the FG pin or I²C. The DRV10975 device incorporates an integrated step-down regulator that can efficiently reduce the supply voltage to 5V or 3.3V to power both internal and external circuits. This device is available in two models with sleep mode and standby mode, enabling energy savings when the motor stops running. The standby mode (4.5mA) model keeps the regulator running, while the sleep mode (80μA) model stops the regulator. Use the standby mode model in applications where the regulator is used to power an external microcontroller. Users can reprogram specific motor parameters in the registers and program the EEPROM via the I²C interface to help optimize the performance of a given application. The DRV10975 device is packaged in a high-efficiency thermal HTSSOP 24-pin package with an exposed thermal pad. It is rated for an operating temperature range of -40°C to 125°C.
