温度监测器和PWM风扇控制器 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.
