PST893B

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. 

MinebeaMitsumiPST893B is a reset IC for turning on/off power supply and power flicker in CPU or logic systems. This IC can change delay time by an external capacitor. Charging method of the capacitor is current source type. Current source type can reduce temperature fluctuations in the delay time td typ. ±6% (Ta=-40°C to 105°C). It is ideal for a wide range of operating temperature.

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