Reset ICs are integrated circuits that monitor the power supply voltage in CPU and other logic systems, initiating a system reset during power-on or when a momentary power interruption (brownout) is detected.
We support the creation of robust circuits.
Our comprehensive range of Reset ICs includes various feature sets, such as built-in delay circuits, separated sense inputs, manual reset functions, and integrated timers. All products offer high accuracy, low current consumption, and a wide detection voltage range, ensuring a broad portfolio to support your diverse system requirements.

Overview

This is a reset IC with an independent voltage detection monitor terminal VS and VDD terminal.
The IC power supply is separate and so, even if the monitor voltage VS is low, the output does not become unstable at the operation limit like conventional reset ICs. Instead it maintains low-level operation.
This IC is particularly suitable for low-voltage (1V type) power monitoring. It has an accuracy of ±1.5% and an ultralow current consumption of 0.35 µA typ. And otherwise offers characteristics resembling those of conventional IC reset ICs.
