FAN CONTROLLER
Figure 14 shows a simple fan controller that will switch ON a
cooling fan when the temperature exceeds 80
°
C and switch it
OFF again when the temperature falls below 75
°
C. The AD7416
can be used standalone in this application or with a serial bus
interface if different trip temperatures are required. If the AD7416
is used with a bus interface, the sense of OTI can be set to active
high, Q1 and R1 can be omitted, and OTI can be connected
directly to the gate of Q2 with R2 as the pull-up resistor.

THERMOSTAT
Figure 15 shows the AD7416 used as a thermostat. The heater
will be switched ON when the temperature falls below T

and switched OFF again when the temperature rises above
T
OTI
. For this application and for comparator mode, the OTI
output should be programmed active low.

SYSTEM WITH MULTIPLE AD7416S
The three LSBs of the AD7416
’
s serial address can be set by the
user, allowing eight different addresses from 1001000 to 1001111.
Figure 16 shows a system in which eight AD7416s are connected
to a single serial bus, with their OTI outputs wire-ANDed
together to form a common interrupt line. This arrangement
does mean that each device must be read to determine which
one has generated the interrupt, and if a unique interrupt is
required for each device, the OTI outputs can be connected
separately to the I/O chip.
