| ACE301 Technology Description High-precision Low Voltage Detector ACE301 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. ACE301 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. ACE301 is available in SOT-89-3, SOT-23-3 TO-92, SOT23-5, packages which is Pb free.
