MC33771x datasheet specifies RESET deglich filter time as tRESERFLT 100 us (typ).

Could you confirm maximum deglitch filtetr time?

It is important to specify RESET pulse wideth which will not to fail RESET.

Hello Matsunaga,

The maximum deglitch filter time for the MC33771x is 1 ms. This means that the RESET input must be held low for at least 1 ms in order to guarantee that the device will reset.

The RESET pulse width must be at least 100 us in order to guarantee that the device will reset.

Here is a table from the MC33771x datasheet that summarizes the RESET input requirements:

Requirement Value
RESET input minimum level0 V
RESET input maximum level3.6 V
RESET input pull-up resistance10 kΩ
RESET input deglitch filter time100 us (typ)
RESET pulse width100 us (min)
