ELM73xxxxxA CMOS Voltage detector with delay circuit and Manual Reset function
■General description
ELM73xxxxxA is CMOS voltage detector IC with delay function; delay time is adjustable by external
capacitor. It operates with very low current consumption; 260nA(typ.). The type with Manual Reset function
is also available in ELM73xxxBxA series; reset condition can be manually asserted at any time. There are two
output forms available; N-ch opendrain and CMOS output. The output logic is positive, therefore, the output
becomes low level when VDD is lower than detection voltage. The standard detection voltages are 2.2V, 2.7V,
3.0V and 4.0V; ELM73 series can also be made as semi-custom IC within the range of 1.4~5.0V by 0.1V step.
■Features
• Detection voltage range
: 1.4V to 5.0V (by 0.1V step)
• Low power operation
: Typ.260nA(Vdd=VdetN+1V)
• Accuracy of detection voltage : ±30mV (VdetN<2.5V)
±1.2% (VdetN≥2.5V)
• Accuracy of delay time
: Typ.15% (ExtC=4.7nF)
• Hysteresis voltage
: Typ.VdetN×1.04
• Manual reset input
: MR pin (ELM73xxxBxA only, Built-in pull-up resistor)
• Package
: SC-82AB(SOT-343), SC-70-5(SOT-353), SOT-25
■Application
• Reset for microcomputers
• Voltage power shortage detectors
• Switch of back up power source
• Battery checkers
■Maximum absolute ratings
