PST851A

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 PST851A is a reset IC with an independent voltage detection monitor terminal VS and VDD terminal. The IC power supply is separate. 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 type and otherwise offers characteristics equivalent to those of conventional reset ICs.

MinebeaMitsumi reset circuits are made in Japan and are of the highest quality. They will be perfectly suited for your applications.
