Description
The R3111x series are CMOS-based voltage detector ICs designed for system reset and are commonly used as input power voltage level detectors for microprocessors, microcontrollers, ASICs and FPGAs. They have high detector threshold accuracy and a ultra-low supply current allowing operation at an extremely low voltage. Each of these ICs consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver and a hysteresis circuit. Six types of packages are available, TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
