Microchip EMC2301-1-ACZL-TR

风扇控制3V ~ 3.6V

Overview

The EMC2301-1-ACZL-TR is an SMBus compliant fan controller with a PWM fan driver. The fan driver is controlled by a programmable frequency PWM driver and Fan Speed Control algorithm that operates in either a closed loop fashion or as a directly PWM-controlled device.

Additionally, the EMC2301-1-ACZL-TR offers a clock output so that multiple devices may be chained and slaved to the same clock source for optimal performance in large distributed systems.
