R3111N331A-TR-F - Brand New RICOH IC Chips
-
Description
The R3111N331A-TR-F is a CMOS-based voltage detector IC in the R3111x series. It is known for its high detector threshold accuracy and ultra-low supply current. This IC is commonly used for system reset applications. It consists of a voltage reference unit, comparator, resistors for detector threshold setting, output driver, and hysteresis circuit. The detector threshold is fixed internally with high accuracy and does not require adjustment. The R3111N331A-TR-F is available in three output types: Nch open drain "L" type, Nch open drain "H" type, and CMOS type. It operates at a lower voltage compared to the Rx5VL series and can be driven by a single battery. It comes in six different package options: TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
