STM32 MCUs with more than 3 complementary PWM Channels

[TwixMeow]

Hey,

currently im evaluating STM32F401ReX, but it seems like it has only 3  complementary PWM Channels on Timer 1. Are there any Controllers with a total of 6 complementary PWM channels?

Hello @TwixMeow and welcome to the ST Community :smiling_face_with_smiling_eyes:.

I suggest you to take a look at the STM32G4 Series (refer to the RM0440).

Best Regards.

The G4 has 4 on timer 1, 8 and 20. But they dont work really in my case... (cant keep complemenary on). I think the CHx have to be choosen for a steady on of a channel (for a LS mosfet for example).

Select any MCU with multiple Advanced timers (TIM1,TIM8,TIM20) like STM32G4747 etc. Use feature "timer-link" to synchronize two or more timers and then you can realize many synchronized complementary PWM channels. Note that also some "general purpose" timers have also one or more complementary outpus (like TIM15, TIM16, TIM17).

Did you consider HR-Timers?
