4. Protection circuits
Due to the system structure of the protection circuit for shorts to VCC or ground, if there is a DC resistance
between the amplifier output pins and ground, the protection circuit may operate when power is first applied and
the amplifier may fail to turn on. The basic design approach we recommend is not to adopt any designs in which
there is a DC resistance between the amplifier outputs and ground.
The LA4625 includes a built-in thermal protection circuit to prevent the IC from being damaged or destroyed if
abnormally high temperatures occur. This thermal protection circuit gradually reduces the output if the IC
junction temperature (Tj) reaches the range 170 to 180
°C due to inadequate heat sinking or other problem. If the
temperature falls, the amplifier will restart automatically.
The LA4625 also includes other protection circuits. Use of these circuits also requires care during end product
design and testing.
5. Other notes
The LA4625 is a BTL power amplifier. When testing this device, the ground systems for the test equipment
connected to IC inputs, and that for the test equipment connected to IC outputs, must be isolated. Do not use a
common ground.
