Nisshinbo Micro Devices Inc. RP300K28DA-TR

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