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 IC is a reset IC for turning on/off power supply and power flicker in CPU or logic systems.
The IC applies to the small battery(Li-ion,Li-pol) equipment by high accuracy 1.0% max. and low supply current 0.25µA typ.
PST86XX is compatible with PST82XX.
