MAX6653 Datasheet (Maxim) - Temperature Monitors and PWM Fan Controllers

MAX6653, Temperature Monitors and PWM Fan Controllers

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.
