M62720GP Voltage Detecting, System Resetting IC Series REJ03D0522–0100 Rev.1.00 May 27, 2005 Description The M62720GP 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) • Wide supply voltage range 1.5V to 7.0V • Wide application range • Extra small 3-pin package (3-pin SOP) • Built-in long delay time 0.65V (Typ.) at RL=22kΩ 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 Rev.1.00 May 27, 2005 page 1 of 4 M62720GP Pin Arrangement TOP VIEW GND 2 OUTPUT 1 SUPPLY VOLTAGE 3 M62720GP Outline SOT–23 Block Diagram SUPPLY VOLTAGE 1 R1 + R2 2 OUTPUT OSC – COUNTER 1.25V 3 GND Function Diagram "L"RESET TYPE SUPPLY VOLTAGE 3.70V 0.65V t H OUTPUT STATE td td L t OUTPUT UNDEFINED Rev.1.00 May 27, 2005 page 2 of 4 td = 50msec M62720GP Absolute Maximum Ratings (Ta = 25°C, unless otherwise noted) Item Supply voltage Symbol VCC Ratings 7 Unit V Isink VO Pd Kθ Topr Tstg 6 VCC 200 2 –30 to +85 –40 to +125 mA V mW mW/°C °C °C Output sink current Output voltage Power dissipation Thermal derating Operating temperature Storage temperature Test Conditions Output with constant current load 3pin SOP (SOT-23) Ta ≥ 25°C 3pin SOP Electrical Characteristics (Ta = 25°C, unless otherwise noted) Symbol Min Typ Max Unit Detecting voltage Hysteresis voltage Detecting voltage temperature coefficient Circuit current Output saturation voltage Threshold operating voltage VS ∆VS VS/∆T 3.56 50 3.70 80 0.01 3.86 110 V mV %/°C ICC Vsat 400 0.2 600 0.4 µA V VOPL 0.7 0.6 0.8 0.7 V Output load current Output high voltage Propagation delay time IOC VOH tpd –40 VCC–0.2 30 –25 –17 70 µA V ms Item VCC–0.06 50 Test condition VCC = 5.0V VCC=3.5V, Isink=4mA, Minimum RL=2.2kΩ, Vsat≤0.4V supply voltage for operation RL=100kΩ, Vsat≤0.4V VCC = 5.0V, VO=1/2VCC Example of Application Circuit Reset Circuit of M62720GP Vcc SUPPLY VOLTAGE OUTPUT M62720GP GND SUPPLY VOLTAGE RESET (RESET) LOGIC CIRCUIT GND Note: 1. 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.
