■GENERAL DESCRIPTION
ELM 75xxxxA Series is improved CMOS voltage detector ICs available in very small package SC-
82AB.Compared to ELM97xxxxA Series, lower current consumption TYP.0.6μA (VDD=4.5V) and higher
accuracy (±2.0%) of detection voltage are achieved. It consists of a very low-power-consumption refer-
ence voltage source, a hysteresis comparator, an output driver, and detection voltage setting resistors.
Output logic is positive, therefore output level is low when VDD is lower than detection voltage.
It can be used as reset controller in microcomputer-based systems. In addition, it can be widely applied to
the devices, such as battery checkers, switching circuit of back-up power source, power failure detectors,
etc. Two output styles are available, N-ch opendrain and CMOS output.
