ZCC575A 数字温度传感器替代LM75DescriptionThe 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 FQresistersetting.Features■ Temperatureaccuracy‐ ±1℃ from -20℃~80℃‐ ±2℃ from -40℃~125℃■ Lowpowerconsumption• 4.5uA shutdown current atVDD=5.0V• 125uA continuous conversioncurrent■ 2.2~8.0Vultra-wide operation supplyvoltage■ High PSR intemperaturemonitoring■ I2C &SMBusdigital communicationinterface■ LM75 function andregistercompatible■ 0.0625℃ temperatureresolution■ Supportup to 32 devices by A0/A1/A2 pin hardware configuration■ OS pin open-drain alert and interruptmulti-function■ OS outputpolarityconfiguration■ Embedded one-shotconversionmode Applications■ Home appliancethermalcontrol■ Server boardtemperaturemonitoring■ Thermostatcontrol■ Environmentaltemperaturemonitoring■ Electronicequipment andfacilities■ General systemthermalmanagement
