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.
