科瑞芯电子供应 PT2509 普诚同步电机驱动器
DESCRIPTION
PT2509 is a full-bridge driver with build-in drivingpattern for the swing head motor application.It integrates the over temperature protection, shortcircuit protection, and under voltage protection. Withone EN control pin, the PT2509 will deliver 50HzPWM waveform to drive the AC synchronous motor.Besides the 50Hz pattern, a clock signal can alsofeed to EN pin to operate with required frequency.PT2509 with package in SOP8.
