ALARM OUTPUTS
(TEA3718SP - TEA3718DP)
The alarm output becomes low when the junc-
tion temperature reaches T
°
C.
When an alarm condition occours, parts of the
supply voltage (dividing bridge R - R
C
) is fed to
the comparator input pin (Fig. A)
Depending of the R
C
C value the behaviour of
the circuit is different on alarm condition:
1) R
C
> 80
the output stage is switched off
2) R
C
> 60
the current in the motor windings
is reduced according to the approximate formula:
(see also fig. E and F)
with V
TH
= Threshold of the comparator (V

(typical)
For several Multiwatt packages a common de-
tection can be obtained as in Fig. D
PRE-ALARM OUTPUT
When the junction temperature reaches T1
°
C
(typ. = 170
°
C) a prealarm signal is generated.
