TI公司的DRV10987是50W 12V-24V三相無傳感器BLDC馬達驅動器,集成了功率MOSFET,提供連續(xù)驅動電流高達2A,馬達工作電壓6.2V-28V,集成了降壓轉換器5V/100mA,LDO 3.3V/20mA,主要用在空氣凈化器和加濕器,三向BLDC和PMSM馬達,烘干循環(huán)風機,排水和水泵,臺扇和吊扇.本文介紹了DRV10987主要特性,框圖,應用電路圖以及評估模塊DRV10987 EVM主要特性,電路圖,材料清單.
The DRV10987 device is a 3-phase sensorless 180°sinusodial motor driver with integrated powerMOSFETs, which can provide continuous drivecurrent up to 2 A. The device is specifically designedfor cost-sensitive, low-noise, low-external-componentcount fan and pump applications.™
The DRV10987 device delivers current to the motorwith supply voltage as low as 6.2 V. If the powersupply voltage is higher than 28 V, the device stopsdriving the motor and protects the DRV10987circuitry.
The DRV10987 device 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 interfaceto the device is designed to be simple and flexible. The motor can be controlled directly through PWM, analog, orI2C inputs. Motor speed feedback is available through both the FG pin and the I2C interface simultaneously.
The DRV10987 device features an integrated buck regulator to step down the supply voltage efficiently to 5 V forpowering both internal and external circuits. The 3.3-V LDO also may be used to provide power for externalcircuits. The standby-mode (8.5 mA) version (DRV10987S) leaves the regulator running, and the sleep-mode (48μA) version (DRV10987D) shuts the regulator off. Throughout this data sheet, the DRV10987 part number isused for both devices, that is, DRV10987D (sleep version) and DRV10987S (standby version), except for specificdiscussions of sleep vs standby functionality.
An I2C interface allows the user to rEPROgram specific motor parameters in registers and to program theEEPROM to help optimize the performance for a given application. The DRV10987 device is available in athermally-efficient HTSSOP, 24-pin package with an exposed thermal pad. The operating ambient temperature isspecified from –40℃ to 125℃.
