V
4MON
can be used with V
4OUT
intandem to form a simple PWM
control circuit. For example as shown in Figure 27, when a
temperature sensor output connects to the V
4MON
input, with
the proper threshold level set, V
4OUT
outputs high whenever the
temperature goes above the threshold. This turns on the FET
switch which activates the fan. When Vtemp drops below the
threshold, V
4OUT
decreases which turns off the fan.

Battery State of Charge Indicator and Shutdown
Early Warning Monitoring
In the automotive application, the system designer may set the
battery threshold to the lowest level in order to allow an
automobile to start at the worst case condition. If the battery
remains at the low voltage level, it is indeed a poor battery.
However, there is no way to warn the driver. As a result, the
system designer may use V
4OUT
as the battery warning indicator.
By stepping down the battery voltage monitored at V
4MON
, the
LED is lit which gives a battery replacement warning. The
circuit is shown in Figure 29.
