R3111H301C-T1-F - Brand New RICOH IC Chips
-
Description
The R3111H301C-T1-F is a CMOS-based voltage detector IC from the R3111x series. It is designed with high detector threshold accuracy and ultra-low supply current, making it an ideal choice for system reset applications. The IC consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, and a hysteresis circuit. With its fixed and highly accurate detector threshold, no adjustment is needed. It offers three output types: Nch open drain "L" type, Nch open drain "H" type, and CMOS type. The R3111H301C-T1-F can be operated at a lower voltage than the Rx5VL series and can be powered by a single battery. It is available in six different packages: TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
