BKIN Input to shutdown PWM for motor

[sag]

Hi, i have configured BKIN pin to detect fault for my overcurrent

So for my motor driver if this pin sense BKIN input. 

How much time it be will taken by my microcontroller to sense and to act to shutdown my PWM gate signals

Is it hardware glued logic that can work independently fast without existing code running

Please give any value in micro or nano seconds how much fast it can operate.

Also any effect of maximum temperature which can cause delay in to it like ambient 125 deg C as device's \max temp range, is it temperature dependent.

Below are details

Hello @sag, 

1/ The BKIN is designed to act asynchronously, meaning it can disable the PWM outputs immediately upon detecting a fault, the exact response time is not explicit but given the high-speed nature of the STM32G4, I it's in the order of nanoseconds 

2/ yes, it is hardware-implemented

3/ given that the STM32G4 microcontrollers are designed to operate within a specified temperature range, the break input functionality should remain reliable within this range
