BUILT-IN PROTECTION SYSTEMS

Load dump voltage surge

The TDA 2003 has a circuit which enables it to

withstanda voltagepulse train,on pin 5, of the type

shown in fig. 19.

If the supply voltage peaks to more than 40V, then

an LC filter must be inserted between the supply

and pin 5, in order to assure that the pulses at pin

5 will be held within the limits shown in fig. 18.

A suggested LC network is shown in fig. 19. With

this network, a train of pulses with amplitude up to

120V and width of 2 ms can be applied at point A.

This type of protection is ON when the supply

voltage(pulsedor DC)exceeds18V.Forthisreason

the maximum operatingsupply voltage is 18V.

Short-circuit (AC and DC conditions)

In particular, the TDA 2003 can drive a coupling

transformerfor audio modulation.

The TDA 2003 can withstand a permanent short-

circuit on the output for a supply voltage up to 16V.

DC voltage

The maximum operating DC voltage on the TDA

2003 is 18V.

Howeverthe devicecan withstanda DCvoltage up

to 28V with no damage. This could occur during

winter if two batteries were series connected to

crank the engine.

Polarity inversion

High current (up to 5A) can be handled by the

device withno damagefor a longerperiod thanthe

blow-out time of a quick 1A fuse (normally con-

nected in series with the supply).

This featureis added to avoiddestruction if, during

fitting to thecar, a mistakeon the connectionof the

supply is made.

Thermal shut-down

Thepresence of a thermal limitingcircuit offers the

following advantages:

Open ground

1) an overload on the output (even if it is perma-

nent),oran excessive ambient temperaturecan

be easily withstood.

2) the heat-sink can have a smaller factor com-

pared with that of a conventionalcircuit.

When the radio is in the ON condition and the

ground is accidentally opened, a standard audio

amplifier will be damaged. On the TDA 2003 pro-

tection diodes are included to avoid any damage.

Inductive load

There is no device damage in the case of ex-

cessive junction temperature: all that happens

is thatP_o(andthereforeP_tot) andI_darereduced.

A protectiondiode is providedbetweenpin 4 and5

(see the internal schematic diagram) to allow use

of the TDA 2003 with inductive loads.

PRATICAL CONSIDERATION

Printed circuit board

The layout shown in fig. 17 is recommended. If

different layouts are used, the ground points of

input 1 and input 2 must be well decoupled from

thegroundoftheoutputthroughwhicha ratherhigh

current flows.

packageand the heat-sink.Pinlength shouldbe as

short as possible.The soldering temperature must

not exceed 260 C for 12 seconds.

Application suggestions

The recommended component values are those

shown in the applicationcircuits of fig.16.

Different valuescan be used.The followingtableis
