一.产品概述  

---

       CXDR7531C  CXDR7531D is a series of high precision voltage detector with ultra-low

current consumption (4.5uA typ. at Vin = 3.0V) and a built-in delay circuit.

 It can work at very low voltage, which makes it perfect for system reset.

       CXDR7531C CXDR7531D 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. 

Only CMOS type is available. 

  CXDR7531C  CXDR7531D is available in small size SOT23 package which is Pb free.
