9.4 Power Monitor

The dsPIC33AK256MPS306 device family features a power monitoring system that autonomously scans the internal voltage domains and provides real-time status indication. The purpose of the system is to ensure that critical system resources needed for the application’s key peripherals are within specification. Each voltage domain and the system bandgap are checked for overvoltage (OV) and undervoltage (UV) conditions. If either condition is detected, a device Reset will occur. The power monitoring system includes the following features:

• Autonomous OV and UV detection
• Real-time status indication
• Fault indication storage
• Dedicated trip points for voltage domains and system bandgap
• Independent clock source
• Independent bandgap reference
• Configurable Fault injection
