Cost and space savings
Description
The TDA2003A is capable of providing a high output current (up to 3.5 A) with very low harmonic and crossover distortion.
Completely safe operation is guaranteed due to
DC and AC short-circuit protection between all pins and ground, a thermal limiting circuit, load dump voltage surge protection up to 40 V and protection diodes in case of accidental open ground.

3.1.1
Built-in protection systems
Load dump voltage surge 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
.
A recommended LC network is shown in
. With this network, a train of pulses with 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.

Suggested LC network circuit
3.1.2 Short-circuit (AC and DC conditions)
The TDA2003A can withstand a permanent short-circuit on the output for a supply voltage up to 16 V.
High current (up to 5 A) can be handled by the device with no damage for a longer period than the blow-out time of a quick 1 A fuse (normally connected in series with the supply).
This feature is added to avoid destruction if, during fitting to the car, a mistake on the connection of the supply is made.
When the radio is in the ON condition and the ground is accidentally opened, a standard audio amplifier will be damaged. On the TDA2003A, protection diodes are included to avoid any damage.
allow use of the TDA2003A with inductive loads. In particular, the TDA2003A can drive a coupling transformer for audio modulation.
The maximum operating DC voltage on the TDA2003A is 18 V, however the device can withstand a DC voltage up to 28 V with no damage. This could occur during winter if two batteries were connected in series to crank the engine.
Doc ID 018796 Rev 4 13/19
Application information TDA2003A
The presence of a thermal limiting circuit offers the following advantages:
1.
An overload on the output (even if it is permanent), or an excessive ambient temperature can be easily withstood.
2. The heatsink can have a smaller factor compared with that of a conventional circuit.
There is no damage to the device in the case of excessive junction temperature: only
P o
(and therefore P tot
) and Id are reduced.

L

Ω
)
Figure 25.
Output power and drain current vs. case temperature (R
L
= 2
Ω
)
The layout shown in Figure 21 is recommended. If different layouts are used, the ground
points of input 1 and input 2 must be well decoupled from the ground of the output through which a rather high current flows.
No electrical insulation is required between the package and the heatsink. Pin length should be as short as possible. The soldering temperature must not exceed 260 °C for 12 seconds.
