The number of pwm in TMS570

Thomas Song

A customer is considering TMS570 MCU for On Board Charger application in HEV.  I could not find the terminology for PWM  in TMS570 MCU.

Could you tell me which peripheral is for PWM generation in TMS570? or Could you recommend the MCU for OBC application?

Best regards,

Thomas Song

    Hi Thomas,

    The module you're looking for is the High End Timer, NHET.

    Regards, Tony.

    Hello Thomas,

    the NHET module is a programmable timer and theoretically it can generate as many PWMs as NHET pins are available. However in an application, it depends also on if the PWMs should have different frequencies, on the available NHET memory and the complexity of the program (e.g. synchronous vs asynchronous duty cycle updates, etc.) and other tasks the timer should accomplish (e.g. input capture, pulse generation, period/pulse measurements, SPI emulation...).

    The NHET is very flexible in what can be achieved, but what can be done is very much dependent on the application requirements.

    In general there shouldn't be an issue using it for an HEV application.

    Regards,

    Frank
