ELM76xxxxxxxxC
CMOS Voltage detector with delay function
■General description
ELM76xxxxxxxxC is CMOS voltage detector IC with delay function; external capacitor is unnecessary
for the delay time circuit. There are 4 types of delay time selection of ELM76 series: Typ.50ms, Typ.150ms,
Typ.250ms, Typ.500ms, and ELM76 series can also be made as semi-custom ICs within the range of 30ms
to 500ms by 10ms step. There are two output styles of ELM76 series: N-ch open-drain and CMOS output. In
addition, two output logic modes are available; RESET and RESET. The output level is high for RESET mode
and low for RESET mode when VDD is lower than detection voltage. The standard detection voltages are 1.6V,
2.5V, 2.7V, 3.0V, 4.0V and 5.5V and ELM76 series can also be made as semi-custom ICs within 1.6 to 5.5V by
0.1V step.
