Alarm output (TEA3718SP, TEA3718DP and TEA3718SDP)
The ALARM output pin becomes low when the junction temperature reaches T
° C. When an
alarm condition occurs, parts of the supply voltage (dividing bridge R - RC) is fed to the
comparator input pin (
Figure 16). Depending on the RC value the behavior of the circuit on
an alarm condition is as follows:
●
RC > 80 ohms, the output stage is switched off
●
RC > 60 ohms, the current in the motor windings is reduced according to the
approximate formula: (see also
Figure 18 and Figure 19)
with VTH = threshold of the comparator (VCH, VCM, VCL) R = 700 ohms (typical).
For several Multiwatt packages a common detection can be obtained as in
Figure 17.
