NCT475
Industry Standard Digital
Temperature Sensor in CSP
Package with 2-wire
Interface
The NCT475 is a two-wire serially programmable temperature
sensor with an over-temperature/interrupt output pin to signal out of
limit conditions. This is an open-drain pin and can operate in either
comparator or interrupt mode. Temperature measurements are
converted into digital form using a high resolution (12 bit),
sigma-delta, analog-to-digital converter (ADC). The device operates
over the –55°C to +125°C temperature range.
Communication with the NCT475 is accomplished via the
SMBus/I2C interface which is compatible with industry standard
protocols. Through this interface the NCT475s internal registers may
be accessed. These registers allow the user to read the current
temperature, change the configuration settings and adjust the
temperature limits.
The NCT475 has a wide supply voltage range of 3.0 V to 5.5 V. The
average supply current is 575 mA at 3.3 V. It also offers a shutdown
mode to conserve power. The typical shutdown current is 3 mA.
The NCT475 is available in a space saving 6 ball CSP package as
NCT475A and NCT475B. NCT475B gives I2C address options of …
