RT9818C-28PV - Brand New 30000Richtek IC Chips
-
Description
The RT9818C-28PV is a micro-power voltage detector designed to supervise the power supply voltage level for microprocessors or digital systems. With internally fixed threshold levels ranging from 1.5V to 5V, it is suitable for a wide range of digital applications. It features low supply current of 2.5µA and performs a supervisory function by sending out a reset signal when the VDD voltage falls below the preset threshold level. Once VDD recovers and crosses the threshold level, the reset signal is released after a certain delay time. It is compatible with a small 4-pin SOT-25 package.
