Part Number: TMS320F280045

Hi Experts,

Refer to F28004x TRM, the high-precision Dead-Band of PWM1A & PWM1B could be configured by related registers.

However customer wonder how to configure the high-precision Dead-Band between PWM1A & PWM2A, and what the resolution of high-precision Dead-Band between PWM1A & PWM2A?

Thanks!

Hi Rayna,

I'm investigating what mechanisms can be used to maintain syncronization between the values loaded into the two modules and also the accuracy of the deadband settings module-to-module.

Hi Rayna,

Sorry for the time this is taking. I think we will be able to provide some additional information sometime later this week.

Hi Rayna,

The matching of the HRPWM for different modules should nominally be better than about 5 MEP steps / 750ps across possible HR values.

We don't currently have sufficient characterization data & testing to add this to the data sheet or otherwise guarantee the min/max value of this parameter.
