Nisshinbo Micro Devices Inc. RP300K29DC3-TR

The RP300x is a voltage detector (VD) IC with a built-in output delay circuit. The RP300x is available in internally fixed detector threshold type. When the VDD voltage becomes lower than the preset voltage, the RP300xxxxA/C generates a “L” reset signal and the RP300xxxxB(1) 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 or 200 ms after the VDD voltage rises above the threshold voltage or when manual reset is canceled. The RP300x is designed to ignore fast transients on the VDD 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 a small DFN(PLP)1010-4B package or in a SOT-23-5 package.
