GENERAL DESCRIPTION
The ADT7408 is the first digital temperature sensor that
complies with JEDEC standard JC-42.4 for Mobile Platform
Memory Module. The ADT7408 contains a band gap
temperature sensor and 12-bit ADC to monitor and digitize the
temperature to a resolution of 0.0625°C.
There is an open-drain Event# output that is active when the
monitoring temperature exceeds a critical programmable limit
or the temperature falls above or below an alarm window. This
pin can operate in either comparator or interrupt mode. There
are three slave-device address pins that allows up to eight
ADT7408s to be used in a system that monitors temperature of
various components and subsystems.
The ADT7408 is specified for operation at supply voltages from
3.0 V to 3.6 V. Operating at 3.3 V, the average supply current is
less than typically 240A. The ADT7408 offers a shutdown
mode that powers down the device and gives a shutdown
current of typically 3 A. The ADT7408 is rated for operation
over the –20°C to +125°C temperature range. The ADT7408 is
available in lead-free 8-lead LFCSP 3mm x 3mm (JEDEC MO-
229 VEED-4) package.
