TP7808 详细介绍

General Description
The TP7808 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at Vdd=3.0V). It can work at very low voltage, which makes it perfect for system reset.
The TP7808 is composed of high precision voltage reference, comparator, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming.
Two type of output, CMOS and N-channel open-drain are available available.TP7808 is available in SOT-89-3, SOT-23-3, SOT23-5 packages which is Pb free.
