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.
