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

Single channel

Monitors a single voltage rail for undervoltage or overvoltage detection

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

Multichannel

Monitors multiple voltage rails with high precision

Push-button reset IC

Monitors user presses and provides a reset after the user holds the button for a given time period

Low IQ

Monitors a voltage supply with low-power consumption to achieve longer battery life
