NAME
FUNCTION

1, 15
TH1, TH2
High-Temperature Threshold Inputs. Connect to V
DD
, GND, or
leave unconnected to select the upper fan-control trip
temperature (T
HIGH
), in 5癈 increments. See Table 1.
2, 3
2, 3
TL2, TL1
Low-Temperature Threshold Inputs. Connect to V
DD
, GND, or
leave unconnected to select the lower fan-control trip
temperature (T
LOW
), in 5癈 increments. See Table 2.

FANFAIL
Fan-Fail Alarm Output. FANFAIL is an active-low, open-drain
output. If the FAN_IN_ detects a fan failure, the FANFAIL output
asserts low.

TACHSET
FAN_IN_ Control Input. TACHSET controls what type of fan-fail
condition is being detected. Connect TACHSET to V
DD
, GND,
or leave floating to set locked rotor, current sense, or
tachometer configurations (see Table 3).
6
FULLSPD
Active-High Logic Input. When pulled high, the fan runs at
100% duty cycle.
FULLSPD
Active-Low Logic Input. When pulled low, the fan runs at 100%
duty cycle.
