Outline

This IC functions in a variety of CPU systems and other logic systems, to detect power supply voltage and reset the system accurately when power is turned on or interrupted. This ultra-low current consumption low reset type system reset IC has a built-in delay time generating circuit that can set the time by an external capacitor and resistor. It is ideal for use in multi-CPU systems because a fast-rising output waveform can be obtained.

Features

1. Ultra-low current consumption ICCH=7.5?A typ. ICCL=400?A typ.

2. Low operating limit voltage 0.65V typ.

3. Output current high for ON 30mA typ.

4. Hysteresis voltage provided in detection voltage 50mV typ.

5. Delay time can set over a wide range using

external capacitor and resistor. 10?S~10S

6. 10 ranks of detection voltage

Applications

1. Reset circuits in microcomputers, CPUs and MPUs (especially multi-CPU sets)

2. Logic circuit reset circuits.

3. Battery voltage check circuits.

4. Back-up power supply switching circuits.

5. Level detection circuits.
