VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES

GENERAL DESCRIPTION

The M627XXML/SL is a voltage threshold detector designedfor detection of a supply voltage and generation of a systemreset pulse for almost all logic circuits such asmicroprocessor.

It also has extensive applications including battery checking,level detecting and waveform shaping circuits.

FEATURES

• Detecting Voltage M627X2,M627X3 …… 2.87V M627X4,M627X5 …… 2.58V M627X6,M627X7 …… 2.39V M627X8,M627X9 …… 1.72V

• Hysterisis Voltage ………………………… 80mV • Delay Time M6270X ………… 0sec M6271X ………… 200 µsec M6272X ………… 50msec M6273X ………… 100msec M6274X ………… 200msec• Few external parts

• Low threshold operating voltage (Supply voltage to keep

low-state at low supply voltage) …0.65V(TYP.) at RL=22kΩ• Wide supply voltage range ………… 1.5V to 7.0V

• Sudden change in power supply has minimal effect on the ICs• Extra small 3-pin package (3-pin FLAT)• Built-in long delay time

APPLICATION

• Reset pulse generation for almost all logic circuits

• Battery checking, level detecting, waveform shaping circuits• Delayed waveform generator

• Switching circuit to a back-up power supply• DC/DC converter

• Over voltage protection circuit

RECOMMENDED OPERATING CONDITION• Supply voltage range ………… 1.5V to 7.0VThis product is on during the development, and there is a case rescheduling it future technical standard.PIN CONFIGURATION (TOP VIEW) ex. M62724

The logic circuit preferably should not have a pull-down resistor,but if one is present,add load resistor RL to overcome the pull-down resistor.

!Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable,but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personalinjury,fire or property damage.Remember to give due consideration to safety when making your circuit design,in orderto prevent fires from spreading,redundancy,malfunction or other mishap.
