TDA2003
LINEAR INTEGRATED CIRCUIT
BUILT-IN PROTECTION SYSTEMS
LOAD DUMP VOLTAGE SURGE
The UTC TDA2003 has a circuit which enables it to withstand a voltage pulse train, on pin 5.
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 head within the limits.
A suggested LC network. With this network, a train of pulses with amplitude up to 120V and width of 2ms can be
applied at point A. This type of protection is ON when the supply voltage(pulsed or DC) exceeds 18V. For this
reason the maximum operating supply voltage is 18V.
SHORT CIRCUIT (AC and DC Conditions)
The UTC TDA2003 can withstand a permanent short-circuit on the output for a supply voltage up to 16V.
POLARITY INVERSION
High current (up to 5A) can be handled by the device with no damage for a longer period than the blow-out time
of a quick 1A fuse(normally connected in series with the supply).
The feature is added to avoid destruction if, during fitting to the car, a mistake on connection of the supply is made.
OPEN GROUND
When the radio is in the ON condition and the ground is accidentally opened, a standard audio amplifier will be
damaged. On the UTC TDA2003 protection diodes are included to avoid any damage.
INDUCTIVE LOAD
A protection diode is provide between pin 4 and pin 5(see the internal schematic diagram) to allow use of the
UTC TDA2003 with inductive loads. In particular, the UTC TDA2003 can drive a coupling transformer for audio
modulation.
DC VOLTAGE
The maximum operating DC voltage on the UTC TDA2003 is 18V.
However the device can withstand a DC voltage up to 28V with no damage. This could occur during winter if two
batteries were series connected to crank the engine.
THERMAL SHUT-DOWN
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 heat-sink can have a smaller factor compared with that of a conventional circuit. There is no device damage
in case of excessive junction temperature: all that happens is that Po ( and therefore PD) and Id are reduced.
