ELM75xxxxxxCMOS Small package voltage detector
ELM75xxxxxx is CMOS voltage detector provides lower current consumption-Typ.0.4µA(Vdd=VdetN+1V) and high accuracy (ELM75xxxxxC:±2.0%; ELM75xxxxxD:±1.0%) of detection voltage. It consists of very low-power-consumption reference voltage source, hysteresis comparator, output driver and detection voltage setting resistor. The output is positive logic; therefore, the output becomes low level when Vdd is lower than detection voltage. There are two output styles of ELM75 series: N-ch opendrain and CMOS output. The standard detection voltages are 1.1V, 2.2V, 2.4V, 2.7V. 3.0V and 4.0V; ELM75 series can also be made as semi-custom IC within the range of 0.9 to 5.5V by 0.1V step.
