一.产品概述  

 

---

        CXDR7529 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.

     CXDR7529 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.

      CXDR7529 is available in SOT-89-3, SOT-23-3,TO92, SOT23-5 packages which are Pb free.
