Built-in protection systems
Load dump voltage surge
The TDA2003A has a circuit which enables it to withstand a voltage pulse train, on pin 5, of
the type shown in
If the supply voltage peaks to more than 40 V, then an LC filter must be inserted between
the supply and pin 5, in order to ensure that the pulses at pin 5 will be held within the limits
shown in
A recommended LC network is shown in
amplitude up to 120 V and width of 2 ms can be applied at point A.
This type of protection is ON when the supply voltage (pulsed or DC) exceeds 18 V. For this
reason the maximum operating supply voltage is 18 V.
