Description The ZCC575 is a digital-type high-accurate on-chip integrated temperature sensor chip with an integrated high resolution sigma-deltaconverter and I2C/SMBus digital interface. It is register and functioncompatible with industrial standard LM75 digital temperature sensor. ZCC575 isavailable in E-MSOP8 package, it offers hardwarepin and firmware compatibility to easy upgrade from LM75xdesign. Digital communication 2-wire interface which operates up to 400KHz of fast mode and2.5MHz of high-speed mode. There are 3 hardware address pins, A0/A1/A2, whichcould configure the I2C address externally. The ZCC575has a dedicated over-temperature shutdown output (OS) pin with programmablehigher or lower limit in hysteresis. The OS pin could also be output polarityreverse by configure POL register bit setting in configuration register. Thereis a consecutive fault measurements function which could be programmed by1/2/3/4counts. The OS pin will enabled if the temperature conversion data isover the pre-set limitation value continuously, and satisfies the FQ[1:0]resistersetting.
