Select by type
Single-channel supervisor
Monitors a single voltage rail for undervoltage or overvoltage detection.
Low-IQ supervisor
Monitors a voltage supply with low-power consumption to achieve longer battery life.
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.
Window detector
Monitors overvoltage and undervoltage conditions to alert the system when a voltage rail deviates from the permissible tolerance level.

Power trends
Low quiescent current (IQ)
Achieve ultra-low quiescent current (IQ) without giving up system performance with our wide portfolio of voltage supervisors and reset integrated circuits (ICs). Our low-IQ supervisors provide continuous voltage and power-rail monitoring while operating at low standby power, enabling longer battery run times, faster dynamic response times and a small form factor, all while maintaining ultra-low quiescent power consumption.
