AS3715 − Detailed Description – System Functions

Parameter

Figure 63:

Reset Levels

Reset Levels: Shows the electrical parameter of the voltage supervisors controlling start-up and reset cycles.

Note(s) and/or Footnote(s):

1. It’s recommended to set the ResVoltRise level 200mV above the ResVoltFall level to have a hysteresis.

2. XRES signal is de-bounced with the specified mask time for rising- and falling slope of VBAT.
