TI公司的DRV10983是集成了功率MOSFET的三相無傳感器馬達(dá)驅(qū)動器,連續(xù)驅(qū)動電流高達(dá)2A,輸入電壓8-28V,低噪音低外接元件,馬達(dá)可通過PWM,模擬或I2C輸入進(jìn)行控制,主要用在家用電器風(fēng)扇和HVAC.本文介紹了DRV10983主要特性,框圖,以及評估板DRV10983 EVM主要特性,電路圖和材料清單.
DRV10983 is a three-phase sensorless motor driver with integrated power MOSFETs, which can provide continuous drive current up to 2 A. The device is specifically designed for cost-sensitive, low-noise/low external component count applications.
The DRV10983 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 either the FG pin or I2C.
The DRV10983 features an integrated buck/linear regulator to efficiently step down the supply voltage to either 5 or 3.3 V for powering both internal and external circuits. The device provides a standby mode function to conserve power when the motor is not running. The regulator keeps running and is able to power an external microcontroller in the standby mode.
An I2C interface allows the user to reprogram specific motor parameters in registers and program the EEPROM to help optimize the performance for a given application. The DRV10983 is available in a thermally-efficient HTSSOP, 24-pin package with an exposed thermal pad. The operating temperature is specified from –40℃ to 125℃.
