19-2865; Rev 1; 12/03 MAX6653/MAX6663/MAX6664 Temperature Monitors and PWM Fan Controllers General Description The MAX6653/MAX6663/MAX6664 are ACPI-compliant local and remote-junction temperature sensors and fan controllers.
These devices measure their own die temperature, 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 temperature measurement accuracy is ±1°C from +60°C to +100°C.
Temperature measurement resolution is 0.
125°C 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 temperature...
