Description
R3132D25EA-TR-FE is a CMOS-based low voltage detector IC with built-in delay circuit, high Detector Threshold accuracy, and ultra-low supply current. It is designed to be operated at low voltage and can be used as a system reset generator. This IC consists of a voltage reference, a comparator, resistors for setting voltage detector threshold, an output driver transistor, and an output delay generator. The detector threshold is fixed internally with high accuracy and requires no adjustment. When the supply voltage crosses a setting detector threshold voltage from a high value to a lower value, this IC generates a reset signal. R3132D25EA-TR-FE outputs "L" at detection mode.
