PS9650AH
- Description
- PS9650 is an Intelligent Power Module (IPM)that contains dual cores, controller, drive and power devices in apackage. The high-performance motor drive chip incorporates ME core and 8051 core. ME core integrates FOC, MDU, LPF, PID and SVPWM modules which allow for automatic calculation of FOC or square wave control by hardware used for sensored/sensorless BLDC motors. 8051 core is used for parameter configuration and routine processing. Most of 8051 core instruction cycle takes 1 or 2 clock cycle(s). The dual cores work in parallel to achieve high-performance
motor control. The chip integrates high-speed operational amplifiers, comparators, high-speed ADC, CRC, I2C, UART, Timers and high-speed LDO, which are essential for FOC or square wave control based BLDC motors.
Package of PS9650 is QHFBP8080-60L.
