MAX6660
Remote-Junction Temperature-Controlled
Fan-Speed Regulator with SMBus Interface
_______________________________________________________________________________________

Note 1: Junction Temperature = TA. This implies zero dissipation in pass transistor (no load, or fan turned off).
Note 2: TRJ, Remote Temperature accuracy is guaranteed by design, not production tested.
Note 3: Guaranteed by design. Not production tested.
Note 4: The MAX6660 includes an SMBus timeout, which resets the interface whenever SMBCLK or SMBDATA has been low for
greater than 25ms. This feature can be disabled by setting bit 2 of the Fan Gain register at 16h/1Bh to a 1. When the timeout
is disabled, the minimum clock frequency is DC.
Note 5: Note that a transition must internally provide at least a hold time in order to bridge the undefined region (300ns max) of
SMBCLK’s falling edge.
ELECTRICAL CHARACTERISTICS (continued)
(VCC = +3V to +5.5V, VVFAN = +12V, TA = -40°C to +125°C, unless otherwise specified. Typical values are at VCC = +3.3V and
TA = +25°C.) (Note 1)
