MAX1617A
EVALUATION KIT AVAILABLE
________________General Description
The MAX1617A is a precise digital thermometer that
reports the temperature of both a remote sensor and its
own package. The remote sensor is a diode-connected
transistortypically a low-cost, easily mounted 2N3904
NPN typethat replaces conventional thermistors or ther-
mocouples. Remote accuracy is ?癈 for multiple transis-
tor manufacturers, with no calibration needed. The remote
channel can also measure the die temperature of other
ICs, such as microprocessors, that contain an on-chip,
diode-connected transistor.
The 2-wire serial interface accepts standard System
Management Bus (SMBus) Write Byte, Read Byte, Send
Byte, and Receive Byte commands to program the alarm
thresholds and to read temperature data. The data format
is 7 bits plus sign, with each bit corresponding to 1癈, in
twos complement format. Measurements can be done
automatically and autonomously, with the conversion rate
programmed by the user or programmed to operate in a
single-shot mode. The adjustable rate allows the user to
control the supply-current drain.
The MAX1617A is nearly identical to the popular MAX1617,
but has improved SMBus timing specifications, improved
bus collision immunity, software manufacturer and device
identification available via the serial interface, and a power-
on reset function that can force a reset of the slave address
via the serial interface.
