PST853A-PST854A

MinebeaMitsumi's RESET ICs are trusted by customers worldwide for their high precision, ultra-low power consumption, and comprehensive product lineup. MinebeaMitsumi PST853A and PST854A are system reset devices designed to detect power-off events or power flicker in the power supply of CPUs or logic systems. They feature a delay timeset by an external capacitor and includes a separate sense pin. The reset output does not activate unless the sensed voltage falls below a defined minimum operating threshold, thanks to the separation of the sense and power supply pins. This makes these ICs particularly suitable for low-voltage detection applications.

PST853A and PST854A features :

• Low current consumption
• High accuracy detection
• Separated sense pin

PST853A and PST854A applications :

• Reset circuits for microcomputers, CPUs and MPUs
• Reset circuits for logic circuits
• Battery voltage check circuits
• Back-up power supply switching circuits
• Level detection circuits
