9 / 47 page TDA8933_1 © NXP B.V. 2007. All rights reserved. Preliminary data sheet Rev. 01 — 15 May 2007 9 of 47 NXP Semiconductors TDA8933 Class-D audio amplifier (1) Where: fosc = oscillator frequency (Hz) Rosc = oscillator resistor (Ω) (on pin OSCREF) Table 5 summarizes how to configure the TDA8933 in master or slave configuration. 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.
