Supervisory Circuits

We offer a comprehensive portfolio of voltage supervisors and reset ICs, including watchdog timers, push-button controllers, voltage detectors, fixed time-delay supervisors, and programmable time-delay supervisors. Also referred to as voltage monitors, these devices continuously track system health to ensure stable and reliable operation. With a broad range of integrated features, our supervisors provide the flexibility needed for applications across automotive, industrial, and personal electronics sectors.
Supervisory circuits serve a variety of purposes, with two core functions:

Power-On Reset (POR): During system startup, the supervisor holds the microcontroller in reset until the supply voltage reaches and stabilizes at the correct level.

Undervoltage Reset: The supervisor immediately resets the microcontroller if the supply voltage drops below a defined threshold—either during power-down or a brown-out event.

Supervisors are designed to monitor and manage voltage rails in electronic systems, often interfacing with microcontrollers to maintain power integrity. There are several types of supervisory solutions, including:
