IC for CMOS System Reset PST4X6MXXXN, PST4X6NXXXU

IC for CMOS System Reset

Monolithic IC PST4X6MXXXN, PST4X6NXXXU Series

Outline

This system reset IC was developed using the CMOS process. Ultra-low current consumption of 0.5µA typ.

has been realized through use of the CMOS process. Also, the built-in fixed delay timer provides accurate

reset by detecting power supply voltage during power on and power interruptions.

Features

1 Detection voltage precision

2 Low current consumption

3 Hysteresis
