Hi all, I try to understand break input.I read break input title in datasheet.Refer to  ''The break functionprotects power switches driven by PWM signals generated with the advanced timers.'' in  the datasheet. But I didn't understand power switches there.Which power switches? Can I only connect 3,3v or gnd to BKIN Pin(pA6).Can you give information briefly about it?Can you help me?

Motor control type applications, using external power control circuits (switches) supplying higher current / voltages

Break Input, providing a means to leave the PWM outputs to the external switches in a safe state

Hi berk.ata,

I recommend you to have a look to the

I suppose ı understand.Briefly,Break input leave pwm outputs for  hold harmless motors etc(power circuit..) Ä°s that so?
