This system reset IC, developed using the CMOS process, has a built-in delay function. Ultra-low
consumption current of 1.0µA (typ.). has been achieved through use of the CMOS process. Also, detection
voltage is high-precision detection of ±2%. The small package SSON-4A (1.1 1.4 0.6mm) is used for space
saving.
1. Ultra-low current consumption
2. High-precision detection voltage
3. Operating range
4. Wide operating temperature range
5. Detection voltage
6. Delay time can be easily set with an external component (capacitor).
SOT-25A (PST35XXNR, PST36XXNR)
SC-82ABA, SC-82ABB (PST36XXUR, PST36XXUR)
SSON-4A
1. Reset circuits for microcomputers, CPUs and MPUs
2. Reset circuits for logic circuits
3. Battery voltage check circuits
4. Back-up power supply switching circuits
5. Level detection circuits
6. Delay time can be easily set with an external component (capacitor).
