供应普诚 PT2514 无刷直流电机驱动芯片
DESCRIPTION
PT2514 is an integrated three-phase sensorless BLDCmotor driver chip with advanced protection functions,including soft-start circuit, thermal shutdown, lock onprotection and output current protection. PT2514 usessine wave current control to reduce electromagneticnoise during operation, and is suitable for fan motordrives that require high efficiency. On the speedcontrol interface, it supports PWM or VSP (DC)commands, so that the motor can be controlledsmoothly from low speed to high speed.
PT2514 adopts the BCD process, only a single VDDpower supply is needed for use, and only a few partsare needed around it. The chip is packaged as TSSOP24 with bottom heatdissipation, which can achieve excellent energyefficiency, making it compact, low-cost, and Idealsolution for sensor BLDC motor drive.
APPLICATIONS
● Three phase sensorless BLDC driver
● CPU,GPU, or server cooling fan
