4.1 BOD - Brown-out Detector

4.1.1 Introduction

The MCC Melody Brown-out Detector (BOD) System driver generates APIs to support BOD-specific peripheral functionality on AVRxxxDx and ATtiny target MCUs.

The BOD monitors the power supply and compares the supply voltage with the programmable brown-out threshold level. The brown-out threshold level defines when to generate a System Reset. The Voltage Level Monitor (VLM) monitors the power supply and compares it to a threshold higher than the BOD threshold. The VLM can then generate an interrupt as an “early warning” when the supply voltage is approaching the BOD threshold. The VLM threshold level is expressed as a percentage above the BOD threshold level.
