M62782GP Voltage Detecting, System Resetting IC Series REJ03D0524–0100 Rev.1.00 May 27, 2005 Description The M62782GP 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 5-pin package (5-pin SOP) SOT-25 • Built-in long delay time 100ms 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 M62782GP Pin Arrangement TOP VIEW GND 1 SUB (GND) 2 NC* 3 5 OUTPUT 4 SUPPLY VOLTAGE M62782GP Outline SOT–25 NC: No connection Block Diagram SUPPLY VOLTAGE 4 R1 + R2 5 OUTPUT OSC – COUNTER 1.25V 3 2 1 NC* SUB (GND) GND NC: No connection Function Diagram "L"RESET TYPE SUPPLY VOLTAGE 4.00V VS VS+∆VS VS 0.65V t H OUTPUT STATE td td L t OUTPUT UNDEFINED Rev.1.00 May 27, 2005 page 2 of 4 td ≈ 100msec M62782GP 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 7 200 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 open collector 5pin SOP (SOT-25) Ta ≥ 25°C Electrical Characteristics (Ta = 25°C, unless otherwise noted) Item Detecting voltage Hysteresis voltage Detecting voltage temperature coefficient Circuit current Output saturation voltage Threshold operating voltage Symbol Min Typ Max Unit VS ∆VS VS/∆T 3.84 50 4.00 80 0.01 4.16 110 V mV %/°C ICC Vsat 400 0.2 600 0.4 µA V VOPL 0.7 0.6 0.8 0.7 V 60 100 30 1 140 nA µA ms Output leak current IOH delay time tpd 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 Ta = –30 to +85°C Example of Application Circuit Reset Circuit of M62782GP Vcc SUPPLY VOLTAGE OUTPUT M62782GP SUB (GND) GND RL SUPPLY VOLTAGE RESET (RESET) LOGIC CIRCUIT GND Note: 1.
