It has extensive applications including battery checking, level detecting and waveform shaping circuits. FEATURES * Few external components * Low operating threshold voltage (Supply voltage to keep a output low in a low supply operation) ...0.65V(typ) at RL = 22k * Wide supply voltage range ............ 2V to 7V * High immunity to a sudden supply voltage change * Wide application range * Extra small 3-pin package (3-pin FLAT) APPLICATION * Reset pulse generation for almost all logic circuits * Battery checking, level detecting, waveform shaping circuits * Delayed waveform generating circuit * Switching circuit to a back-up power supply * DC/DC converter * Over voltage protection circuit RECOMMENDED OPERATING CONDITION * Supply voltage range ............ 2V to 7V PIN CONFIGURATION (TOP VIEW) 3 OUTPUT 2 GND VOLTAGE Outline SOT-89 (1) SUPPLY VOLTAGE (2) GND (3) OUTPUT (1) (2) (3) Outline TO-92L BLOCK DIAGRAM SUPPLY VOLTAGE 1 R1 25A typ. 3 OUTPUT R2 1.25V 2 GND (1/3) M62714SL 1 SUPPLY s f is RoEeLhirsamentoitcalimits are r :T P tic a N ep Som A eci Y t t Nnal spRufibcjatciono. change. e IMI i MITSUBISHI Dig./Ana.INTERFACE M62714ML,SL VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES FUNCTION DIAGRAM SUPPLY VOLTAGE 2.58V 0.65V OUTPUT STATE H td L td=200sec OUTPUT UNDEFINED ABSOLUTE MAXIMUM RATINGS (Ta=25C, Unless otherwise noted) Symbol ICC Isink VO Pd K0 Topr Tstg Parameter Supply Voltage Output Sink Current Output Voltage Power Dissipation Thermal Derating Operating Temperature Storage Temperature Test condition Ratings 7 6 VCC 700 500 7 5 -30 to +85 -40 to +125 Unit V mA V mW mW/C C C Output with constant current load 3pin SIL 3pin FLAT 3PIN SIL Ta25C 3PIN FLAT ELECTRICAL CHARACTERISTICS (Ta=25C, Unless otherwise noted) Symbol VS Parameter Detecting Voltage Hysterisis Voltage Detecting Voltage Temperature Coefficient Circut Current Output Saturation Voltage Threshold Operating Voltage Output Load Current Output HIGH Voltage Propagation Deray Time Delay Time Test condition MIN 2.46 50 Limits TYP 2.58 80 0.01 MAX 2.70 110 Unit V mV %/C A V V A V s VS VS/T ICC Vsat VOPL IOC VOH tPHL tPLH tpd VCC=3V VCC=2V,Isink=4mA Minimum supply voltage RL=2.2k,Vsat0.4V for IC operation RL=100k,Vsat0.4V VCC=2V,VO=1/2VCC Response time when Vcc changes H to L Response time when Vcc changes L to H Ta=-30 to +85C -40 VCC-0.2 80 230 0.2 0.7 0.6 -25 VCC-0.06 6 3 200 400 0.4 0.8 0.7 -17 500 s (2/3) s f is RoEeLhirsamentoitcalimits are r :T P tic a N ep Som A eci Y t t Nnal spRufibcjatciono. change. e IMI i MITSUBISHI Dig./Ana.INTERFACE M62714ML,SL VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES Example of application circuit Reset Circuit of M627XX Series VCC SUPPLY VOLTAGE OUTPUT RL SUPPLY VOLTAGE RESET(RESET) LOGIC CIRCUIT M627XX GND Cd GND Note 1. This IC can be used whether or not a pull-up resistor is included in the logic circuit. Note 2. The logic circuit preferably should not have a pull-down resistor. However in the case it has the resistor, the load resistor RL must be much less than the pull-down resistor. (refer to the above application circuit) ! Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury,fire or property damage.Remember to give due consideration to safety when making your circuit design,in order to prevent fires from spreading,redundancy,malfunction or other mishap.
