CT7432 Unfold All
Product Description
CT7432 is a 3-channels (2-channels Remote and 1-channel Local) Temperature Sensor with ±1°C Accuracy and SMBus Digital Interface. It is ideally used in Temperature Sensing and Monitoring Systems, such as Computer, Server and Telecom Equipment System etc.
Product Features

l  Operation Voltage: 2.7V to 5.5V

l  Average Operating Current:16uA (Typ.)at 0.0625 Conv/s, Vcc = 3.3V

l  Shutdown Current: 3.0uA (Typ.)

l  Temperature Accuracy without calibration for each channel:±1oC from 0oC to 100oC

l  12 bit ADC for 0.0625oC resolution

l  Digital interface compatible with SMBus and I2C

l  Temperature Range up to from -64oC to 191oC by setting RANGE bit as 1

l  Programmable high/low-limit ALERT and THERM Temperature with Hysteresis

l  Automatic beta compensation, Serial Resistance Cancellation, n-Factor correction and Thermal Diode Fault Detection for each remote channel

l  Support SMBus ALERT Response Address (ARA)

l  Multiple Slave address options

l  CT7432A SMBus slave address is determined by the pull-up resistor on the THERM pin

l  Temperature Range:

-40oC to 125oC for sensor chip,

-50oC to 150oC for remote diodes
