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=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 Rev.1.00 May 27, 2005 page 1 of 4 M62720GP Pin Arrangement TOP VIEW 2 GND 3 1 M62720GP Outline SOT-23 SUPPLY VOLTAGE OUTPUT Block Diagram SUPPLY VOLTAGE 1 R1 - R2 1.25V OSC COUNTER 2 OUTPUT + 3 GND Function Diagram SUPPLY VOLTAGE 3.70V "L"RESET TYPE 0.65V t H OUTPUT STATE L td td t OUTPUT UNDEFINED td = 50msec Rev.1.00 May 27, 2005 page 2 of 4 M62720GP Absolute Maximum Ratings (Ta = 25C, unless otherwise noted) Item Supply voltage Output sink current Output voltage Power dissipation Thermal derating Operating temperature Storage temperature Symbol VCC Isink VO Pd K Topr Tstg Ratings 7 6 VCC 200 2 -30 to +85 -40 to +125 Unit V mA V mW mW/C C C Test Conditions Output with constant current load 3pin SOP (SOT-23) Ta 25C 3pin SOP Electrical Characteristics (Ta = 25C, unless otherwise noted) Item Detecting voltage Hysteresis voltage Detecting voltage temperature coefficient Circuit current Output saturation voltage Threshold operating voltage Output load current Output high voltage Propagation delay time Symbol VS VS VS/T ICC Vsat VOPL Min 3.56 50 -40 VCC-0.2 30 Typ 3.70 80 0.01 400 0.2 0.7 0.6 -25 VCC-0.06 Max 3.86 110 600 0.4 0.8 0.7 -17 70 Unit V mV %/C A V V Test condition VCC = 5.0V VCC=3.5V, Isink=4mA, Minimum supply voltage for operation RL=2.2k, Vsat0.4V RL=100k, Vsat0.4V IOC VOH tpd 50 A V ms VCC = 5.0V, VO=1/2VCC Example of Application Circuit Reset Circuit of M62720GP Vcc SUPPLY VOLTAGE OUTPUT M62720GP SUPPLY VOLTAGE RESET (RESET) LOGIC CIRCUIT GND 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.
