SHORT CIRCUIT PROTECTION
The UTC 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.
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 above limit ambient temperature can be easily
supported since the TJ can not be higher than 150°C
2).The heatsink can have a smaller factor of safety compared with that of a congenital circuit, There is no
possibility of device damage due to high junction temperature increase up to 150°C, the thermal shut-down
simply reduces the power dissipation and the current consumption.
APPLICATION SUGGESTION
The recommended values of the components are those shown on application circuit of TYPICAL AMPLIFIER
WITH SPLIT POWER SUPPLY. Different values can be used. The following table can help the designer.
