Short circuit (AC and DC conditions)

The TDA2005 can withstand a permanent short-circuit on the output for a supply voltage up

to 16 V.

Polarity inversion

High current (up to 10 A) can be handled by the device with no damage for a longer period

than the blow-out time of a quick 2 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.

Open ground

When the ratio is in the ON condition and the ground is accidentally opened, a standard

audio amplifier will be damaged. On the TDA2005 protection diodes are included to avoid

any damage.

Inductive load

A protection diode is provided to allow use of the TDA2005 with inductive loads.

DC voltage

The maximum operating DC voltage for the TDA2005 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 are series connected to crank the engine.
