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
±1.5%
