LOW VOLTAGE DETECTOR WITH OUTPUT DELAY

[DISCONTINUED PRODUCT] |
|
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 WLCSP-4-P2, high density mounting on boards is possible. |
