General Description
The ET9818C29/L is a micro-power voltage detector supervising the power supply voltage level for microprocessors (μP) or digital systems. It provides internally fixed threshold levels of 2.9V. It features low supply current of 3μA. The ET9818C29/L performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal will last the whole period before VDD recovering. Once VDD recovered up crossing the threshold level, the reset signal will be released after a certain delay time.
