RP300x Series

0.8% Accuracy, Voltage Detector with Delay Function

NO.EA-306-160309

OUTLINE

The RP300x is a CMOS-based voltage detector (VD) IC with a built-in output delay circuit. Internally, a single

IC consists of a voltage reference unit, a comparator, a resistor net for setting detector threshold, a manual

reset circuit, an output delay circuit and an output driver transistor.

The RP300x is available in internally fixed detector threshold type. When the V

voltage becomes lower than

the preset voltage, the RP300xxxxA/C generates a “L” reset signal and the RP300xxxxB (custom IC

)

generates a “H” reset signal. The detector threshold accuracy is as high as ±1.0% when −V

SET*2

< 1.7 V and

±0.8% when 1.7 V ≤ −V

SET

The reset output signal remains asserted for 50 ms, 100 ms (custom IC) or 200 ms after the V

voltage rises

above the threshold voltage or when manual reset is canceled. The RP300x is designed to ignore fast

transients on the V

pin. The output delay time accuracy is as high as ±5.0%.

The RP300x is available in an Nch open drain output type or in a CMOS output type.

The RP300x is offered in an ultra-small DFN(PLP)1010-4B package or in a SOT-23-5 package.

For more information about a custom IC, please contact our sales representatives.

is defined as a preset detector threshold.
