Nisshinbo Micro Devices Inc. RP300N27AA-TR-FE

The RP300x is a voltage detector (VD) IC with a built-in output delay circuit, available in an internally fixed detection threshold type. When the VDD voltage falls below the preset voltage, RP300xxxxA/C asserts a "L" reset signal, and RP300xxxxB(1) asserts a "H" reset signal. Detection threshold accuracy reaches ±1.0% when -VSET(2) < 1.7V, and ±0.8% when 1.7V ≤ -VSET. After the VDD voltage rises above the threshold voltage or a manual reset is released, the reset output signal remains asserted for 50ms, 100ms, or 200ms. The RP300x is designed to ignore fast transients on the VDD pin, with output delay time accuracy up to ±5.0%. Available in N-channel open-drain output or CMOS output types, offered in compact DFN(PL)1010-4B or SOT-23-5 packages.
