ACE302

                                                                                           ACE302                                               Technology Description Low Voltage Detector with Built-in Delay Circuit ACE302 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at Vdd=3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system reset. ACE302 is composed of high precision voltage reference, comparator, delay circuit, 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. ACE302 is available in SOT-23-3 which is Pb free.
