We offer a broad range of voltage supervisors and voltage supervisor ICs from multiple manufacturers.

A voltage supervisor, or voltage supervisor IC, is a device that monitors or supervises a voltage rail and asserts a signal to enable, disable, or reset another device when that monitored rail falls below or rises above a predetermined threshold voltage. The devices are also known as supply voltage supervisors, voltage supervisory circuits, or voltage monitors.

We offer devices that can manage one to 16 channels. The multichannel types can sequence the supplies in any order at both power-up and power-down.

Voltage supervisors are available with threshold voltages from 4.675mV to 98V, and supply voltages from -10V minimum to 100V maximum. Delay times range from 0ms to 180s. Reset types include Active-High, Active-Low, Manual, Open Drain, and other options and combinations.

The devices are available with a wide choice of digital IC case types and pin counts, with single, pack, tape, reel, tray and tube packaging options. Operating temperatures range from -55°C minimum to 150°C maximum.

A number of devices that meet the AEC-Q100 failure mechanism based stress test qualification are offered for automotive applications.

Our voltage supervisor ICs are manufactured by Analog Devices, Diodes Inc., Micrel Semiconductors, Microchip, Onsemi, Renesas, Rohm, Seiko Instruments, ST Microelectronics, Texas Instruments, and others.
