Description

The ZCC575 is a digital-type high-accurate on-chip  integrated temperature sensor chip with an  integrated high resolution sigma-delta converter and  I2C/SMBus digital interface. It is register and function  compatible with industrial standard LM75 digital  temperature sensor. ZCC575 is available in E-MSOP8  package, it offers hardware pin and firmware  compatibility to easy upgrade from LM75x design. Digital communication 2-wire interface which  operates up to 400KHz of fast mode and 2.5MHz of  high-speed mode. There are 3 hardware address pins,  A0/A1/A2, which could configure the I2C address  externally. The ZCC575 has a dedicated  over-temperature shutdown output (OS) pin with  programmable higher or lower limit in hysteresis.  The OS pin could also be output polarity reverse by  configure POL register bit setting in configuration  register. There is a consecutive fault measurements  function which could be programmed by  1/2/3/4counts. The OS pin will enabled if the  temperature conversion data is over the pre-set  limitation value continuously, and satisfies the FQ[1:0]  resister setting
