IC-PST596-598

The RESET IC is an integrated circuit for voltage detection/power monitoring management. It is mainly used to monitor the power supply voltage of CPUs and other logic systems by detecting whether it has reached a specified threshold value. It triggers a system reset when power is turned on or when a momentary power failure (voltage drop) is detected. RESET ICs are widely used in many types of electronic devices such as office equipment and large home appliances. Although MCUs (microcontrollers with built-in reset functions) or other components can perform similar functions, critical safety protection functions can only be reliably ensured by RESET ICs. MinebeaMitsumi's comprehensive lineup of reset ICs includes various features, such as built-in delay circuits, separate detection inputs, manual reset functions, and built-in timers. All products offer high accuracy, low current consumption, and a wide detection voltage range, ensuring a wide range of solutions to meet various system requirements. 

MinebeaMitsumi IC-PST596, IC-PST597 and IC-PST598 are designed for use in a wide range of CPU and logic systems to monitor supply voltage and provide an accurate system reset during power-up or power interruptions. They integrate a fixed delay time generation circuit for stable reset timing. Notably, these system reset ICs feature ultra-compact size and ultra-low current consumption.
