General Description
The MAX6653/MAX6663/MAX6664 are ACPI-compliant
local and remote-junction temperature sensors and fan
controllers. These devices measure their own die tem-
perature, as well as the temperature of a remote-PN
junction and control the speed of a DC cooling fan
based on the measured temperature. Remote tempera-
ture measurement accuracy is ?癈 from +60癈 to
+100癈. Temperature measurement resolution is
0.125癈 for both local and remote temperatures.
Internal watchdog set points are provided for both local
and remote temperatures. There are two comparison
set points for local temperatures and two for remote
temperatures. When a set point is crossed, the
MAX6653/MAX6663/MAX6664 assert either the INT or
THERM outputs. These outputs can be used as inter-
rupts, clock throttle signals, or overtemperature shut-
down signals. Two pins on the MAX6653 control the
power-up values of the comparison set points, provid-
ing fail-safe protection even when the system is unable
to program the trip temperatures. The MAX6653 has
two additional shutdown outputs, SDR and SDL, that
are triggered when the remote or local temperatures
exceed the programmed shutdown set points. The INT
output for the MAX6653/MAX6663 and THERM outputs
for the MAX6653/MAX6663/MAX6664 can also function
as inputs if either is pulled low to force the fan to full
speed, unless this function is masked by the user.
The MAX6653/MAX6663/MAX6664 are available in
16-pin QSOP packages and operate over the -40癈 to
+125癈 temperature range.
