Description

The TDA2005 is a class B dual audio power

amplifier in Multiwatt11 package specifically

designed for car radio applications.

Power booster amplifiers can be easily designed

using this device that provides a high current

capability (up to 3.5 A) and can drive very low

impedance loads (down to 1.6  in stereo

applications) obtaining an output power of more

than 20 W (bridge configuration).

Application information 4.1.7 TDA2005 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 heatsink can have a smaller factor of safety compared with that of a conventional circuit. There is no device damage in the case of excessive junction temperature : all that happens is that Po (and therefore Ptot) and Id are reduced.
