IC for CMOS System Reset PST4XXAXXXN
IC for CMOS System Reset
Monolithic IC PST4XXAXXXN Series
Outline
This is a system reset IC developed using the CMOS process. The CMOS process allows ultra-low current
consumption of 1.5A(typ.). Further, a fixed delay timer is built in, so that supply voltage is verified when the
power is turned on or interrupted to reset the system accurately.
Features
1. Detection voltage accuracy
±1.5% (25C, VDD = VDET + 0.1)
2. Low current consumption
SOT-23 : 1.5A
3. No external capacitor for delay timer required
Built-in delay timer
SOT-23 : 50/100/200/240/400ms
4. Enhanced rank lineup available for detection voltage, package, output configuration and delay timer.
5. Operating temperature range supporting automotive devices -40 ~ +105C.
Package
SOT-23A
Applications
1. Reset circuits for microcomputers, CPUs and MPUs
