M62781GP
VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
GENERAL DESCRIPTION The M62781GP 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 * Few external parts * Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage) ...0.65V(TYP.) at RL=22k * Wide supply voltage range ............ 1.5to 7.0V * Sudden change in power supply has minimal effect on the ICs * Wide application range * Extra small 3-pin package (3-pin SOP) * 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 ............ 1.5to 7.0V
This product is on during the development, and there is a case rescheduling it future technical standard. PIN CONFIGURATION (TOP VIEW)
