Working Principles

ADM1815-20ART-RL7 operates by continuously monitoring the supply voltage. When the voltage falls below the preset threshold (2.0V), it triggers a reset signal. The reset signal remains active for a specific duration determined by the adjustable reset timeout period. This ensures that the system is properly reset and stabilized before normal operation resumes.

Application Field Plans

ADM1815-20ART-RL7 finds application in various electronic systems where voltage monitoring and control are critical. Some potential application fields include: - Microcontrollers and microprocessors - Embedded systems - Power management circuits - Battery-powered devices - Industrial automation systems
