R3117Nxx3 Series AEC-Q100Compliant Low Voltage Detector with SENSE Pin for Automotive Applications
2019-05-25
The R3117Nxx3 is a CMOS-based voltage detector IC 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.
The IC 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, therefore, even if the sense pin voltage becomes to 0V, the output voltage keeps its "L" level.
Two output types, Nch open drain type and CMOS type are available. The R3117Nxx3 supports the SOT-23-5
package.
