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 0.5A 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
±1.5%
2 Low current consumption
0.5A
3 Hysteresis
6.3mV typ. (VTH
≤ 3.08V)
9.5mV typ. (VTH
≥ 3.08V)
4 External capacitor for delay timer not needed. Built-in delay timer
185ms
5 Full rank variations available for detection voltage, package and output configurations.
6 Operating temperature range suitable for car devices
-40~+105C
Package
SOT-23 (PST4X6MXXXN Series)
SC-70 (PST4X6NXXXU Series)
