8.4 Protections

The following protections are implemented in the TDA8933:

• Thermal Foldback (TF)

• OverTemperature Protection (OTP)

• OverCurrent Protection (OCP)

• Window Protection (WP)

• Supply voltage protections

– UnderVoltage Protection (UVP)

– OverVoltage Protection (OVP)

– UnBalance Protection (UBP)

• ElectroStatic Discharge (ESD)

The behavior of the device under the different fault conditions differs according to the

protection activated and is described in the following sections.
