Overview
R3117x SERIES
LOW VOLTAGE DETECTOR with SENSE pin
NO.
EA-186-080617
OUTLINE
The R3117x series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely low voltage and is used for system reset as an example.
Each of these ICs 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 tolerance of the detector threshold is ±15mV (-VDET = 1.
5V) or ±1.
0% (1.
5V -VDET).
Since the sense pin is separated from the VDD pin of the IC, th...
