R3111N091A-TR-FF - Brand New RICOH IC Chips
-
Description
The R3111x series is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low supply current. It is designed to operate at an extremely low voltage and is commonly used for system reset. Each IC in the series consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, and a hysteresis circuit. The detector threshold is fixed with high accuracy internally and does not require any adjustment. The series offers three output types: Nch open drain "L" type, Nch open drain "H" type, and CMOS type. It can be driven by a single battery and is available in six different package types: TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
