RT9818B

電壓檢測器; Internally Fixed Threshold from 1.2V to 5V in 0.1V Step \n ±1.5% High Accuracy \n 3μA Low Supply Current \n No External Components Required \n Quick Reset within 20μs \n Built-In Recovery Delay Options: 0ms, 55ms, 220ms, 450ms\n 0.9V Low Functional Supply Voltage\n N-Channel Open-Drain Output\n Available in Small SC-82, SC-70-3, SOT-23-3, SOT-23-5, and SOT-89 Packages;

The RT9818 is a micro-power voltage detector designed to supervise the power supply voltage levels for microprocessors (μP) or digital systems. It provides internally fixed threshold levels with 0.1V increments, ranging from 1.2V to 5V, covering most digital applications. The device features a low supply current of 3μA. The RT9818 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal persists until VDD recovers and surpasses the threshold level, at which point the reset signal is released after a certain delay time. The RT9818 is available in SC-82, SC-70-3, SOT-23-3, SOT-23-5, and SOT-89 packages. The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
