TC650 Description

The TC650/TC651 are integrated temperature sensors and brushless DC fan speed controllers. The TC650/ TC651 measure their junction temperature and control the speed of the fan based on that temperature, making them especially suited for applications in modern electronic equipment. Temperature data is converted from the on-chip thermal sensing element and translated into a fractional fan speed from 40% to 100%.
