R3134x Series are CMOS-based voltage detector ICs with built-in delay circuit, high detector threshold accuracy, and ultra low supply current, which can operate at low voltage. These ICs can be used as system reset generators, and each of these ICs consists of a voltage reference, a comparator, resistors for setting voltage detector threshold, an output driver transistor, manual reset circuit, and an output delay generator.
The R3134x Series consists of CMOS-based voltage detector ICs with a built-in delay circuit, high threshold accuracy, and ultra-low supply current. These devices operate within an operating voltage range of 0.75V to 6.0V and are designed to generate reset signals when the supply voltage drops below a specific threshold.
The series includes two output types: Nch open drain and CMOS. Key features include a fixed internal detector threshold requiring no adjustment, a built-in delay time of approximately 240ms to maintain reset conditions after release, and availability in DFN(PLP)1212-6, SOT-23-5, and SC-88A packages for high-density mounting.

The R3134x Series outputs 'L' at its detect pin when the supply voltage crosses the setting detector threshold from high to low.
The IC keeps the reset condition for a fixed delay time of 240ms after the supply voltage or manual reset signal is released.
The device operates with a supply voltage ranging from 0.75V to 6.0V at 25°C.
The maximum output current is rated at 20 mA.
