TDA2030A

7.1

Short-circuit protection

The TDA2030A has an original circuit which limits the current of the output transistors. This

function can be considered as being peak power limiting rather than simple current limiting.

It reduces the possibility that the device gets damaged during an accidental short-circuit

from AC output to ground.

7.2

Thermal shutdown

The presence of a thermal limiting circuit offers the following advantages:

t(s) 1. An overload on the output (even if it is permanent), or an above-limit ambient

temperature can be easily supported since Tj cannot be higher than 150 °C.

uc 2. The heatsink can have a smaller factor of safety compared with that of a conventional

d circuit. There is no possibility of device damage due to high junction temperature. If, for

ro any reason, the junction temperature increases up to 150 °C, the thermal shutdown

Obsolete Product(s) - Obsolete P simply reduces the power dissipation and the current consumption.
