R3116x Series *Only R3116N
0.8% Low Voltage Detector with Output Delay for Automotive Applications
The R3116x 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.
This IC consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, a hysteresis circuit and an output delay circuit. The detector threshold is internally fixed with high accuracy (±12mV: -VDET < 1.5V, ±0.8%: -VDET ≥ 1.5V) and does not require any adjustment. The release output delay time is adjustable by the capacitor connected to the CD pin.
Two output types, Nch open drain type and CMOS type are available.
In addition to SOT-23-5 package, an ultra-small DFN1212-4 package are also available for high-density mounting.
