R3132Q41EC - Brand New RICOH IC Chips
-
Description
R3132Q41EC is a CMOS-based low voltage detector IC with a built-in delay circuit, high detector threshold accuracy, and ultra-low supply current. This IC can be used as a system reset generator and 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. The R3132Q41EC outputs "H" in detection mode. Furthermore, it embeds an output delay generator, which keeps the reset condition for a setting delay time when the supply voltage crosses a setting detector threshold voltage from a low value to a higher value. The output delay time can be selected, with a typical value of 240ms. This IC is available in two output types: Nch open drain type and CMOS type. It comes in a SOT23-3 (Mini-mold) package, allowing for high-density mounting on a board.
