Jul 11, 2002 TC6xx controllers provide thermal protection in temperature-sensitive electronics. Fan speed can be programmed by output of remote thermistor or by SMBus communication based commands. Units detect fan wear-out before fan stops rotating by reading rpm data from up to 2 individual fans. Offered in 10-pin MSOP packages, devices have operating voltage range of 3.0 to 5.5 V and temperature range of -40 to +85°C.

Apr 18, 2002 FPC5010S Smart Bypass monitors drive load and speed, and automatically transfers motor from VFD control to across-the-line at full speed. Removing drive from circuit improves efficiency of system by as much as 5%. It also improves harmonic distortion at full load by removing drive from circuit when harmonic content is greatest. Controller continues to monitor demand and, when requirements are reduced, transfers motor back to drive control.
