Dual RPM-Based Linear Fan Controller with Hardware Thermal Shutdown
Datasheet
SMSC EMC2106
5.19
The EMC2106 contains three dedicated output pins, OVERT1#, OVERT2#, and OVERT3#. Each of
these pins is dedicated to reporting interrupts associated with the External Diode 1 channel, the
External Diode 2 channel, and the External Diode 3 channel respectively. These interrupts work in
addition to the general interrupt ALERT#.
The OVERT1#, OVERT2#, or OVERT3# pin will be asserted depending on which channel reported an
error condition. These interrupt pins are not masked though they can be individually disabled by the
user.
The OVERT1#, OVERT2# and/or OVERT3# pins are cleared automatically when the measured
temperature drops below the high limit minus 4°C or exceeds the low limit plus 4°C.
