Voltage Detecting, System Resetting IC Series
REJ03D0525-0200 Rev.2.00 Nov 03, 2005
Description
The M627XXML/SL is a voltage threshold detector designed for detection of a supply voltage and generation of a system reset pulse for almost all logic circuits such as microprocessor. 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 80mV M6270X: 0sec M6271X: 200usec M6272X: 50msec M6273X: 100msec M6274X: 200msec
* Hysterisis voltage * Delay time
* Few external parts * Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage) * Wide supply voltage range 1.5V to 7.0V * Extra small 3-pin package (3-pin FLAT) * Built-in long delay time
0.65V (Typ.) at RL=22k
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 7.0V
