8.4 Protection
The following protection is included in the TDA8932B:
⢠Thermal Foldback (TF)
⢠OverTemperature Protection (OTP)
⢠OverCurrent Protection (OCP)
⢠Window Protection (WP)
⢠Supply voltage protection:
â UnderVoltage Protection (UVP)
â OverVoltage Protection (OVP)
â UnBalance Protection (UBP)
⢠ElectroStatic Discharge (ESD)
The reaction of the device to the different fault conditions differs per protection.
