ELM9709NAA Overview
VOLTAGE DETECTOR ELM 97xxxxA Series is a CMOS voltage detector IC for battery-operated portable devices. It consists of a very low-power-consumption reference voltage source, a parator, an output driver, a hysteresis circuit, and detection voltage setting resistors. Output logic is positive, therefore output level is low when VDD is lower than detection voltage.
ELM9709NAA Key Features
- Low power operation
- Low voltage operation
- High accuracy of detection voltage
- Low temperature coefficient
- APPLICATION
- Reset for microputer
- Battery checker
- Power failure detector
- Switching of back-up power source
