High-Voltage Monitor Input
25.1
Features
• High-voltage input with V_S/2 threshold voltage
• Integrated selectable pull-up and pull-down current sources
• Wake capability for power saving modes
• Level change sensitivity configurable for transitions from low to high, high to low or both directions
25.2
Introduction
This module is dedicated to monitor external voltage levels above or below a specified threshold or it can be used
to detect a wake-up event at the high-voltage MON pin in low-power mode. The input is sensitive to a input level
monitoring, this is available when the module is switched to active mode with the SFR bit EN.
To use the Wake function during low power mode of the IC, the monitoring pin is switched to Sleep Mode via the
SFR bit EN.
