LOW VOLTAGE DETECTOR W ITH OUTPUT DELAY

R3115Zxx1A/C Series

I

OUTLINE

The R3115Z 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, resistor net for detector threshold setting, an

output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed with high accuracy

internally and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available.

Since the package is WL-CSP, high density mounting on boards is possible.
