Description
The R3111Q351A-TR is an IC chip belonging to the R3111x series voltage detector. It is a CMOS-based voltage detector, boasting of high detector threshold accuracy with ultra-low supply current. This chip can operate at extremely low voltage which makes it an ideal system reset device. It is composed of several components that work together such as resistors for detector threshold setting, a comparator, an output driver, and a hysteresis circuit. The detector threshold of the R3111Q351A-TR is fixed with high accuracy internally and doesn't require any adjustments. It comes in three output types which include Nch open drain “L” type, Nch open drain “H” type and CMOS-type. It also has a lower operating voltage which makes it energy-efficient and can be driven by a single battery. The R3111Q351A-TR comes in six different packages such as TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
