Voltage supervisor & reset ICs for system protection
Continuous voltage and power-rail monitoring
We have a wide portfolio of voltage supervisors and reset ICs that includes watchdog timers, push-button ICs, voltage detectors, fixed time delay supervisors and programmable time delay supervisors. Also known as voltage monitors, these devices continuously monitor system health to ensure proper operation. These devices integrate the right combination of features to provide flexibility for customers across all applications, including automotive, industrial and personal electronics.
Browse by supervisor & reset IC type
Window detector
Monitors overvoltage and undervoltage conditions to alert the system when a voltage rail deviates from the permissible tolerance level
Watchdog timer
Prevents freezes or hangs in an MCU and continuously monitors the voltage supply for undervoltage conditions
Push-button reset IC
Monitors user presses and provides a reset after the user holds the button for a given time period
