Note 4:
Junction Temperature = T A . This implies zero dissipation in pass transistor (no load, or fan turned off).
T RJ , Remote Temperature accuracy is guaranteed by design, not production tested.
Guaranteed by design. Not production tested.
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.
