Product data sheet Rev. 04 — 18 December 2008 8 of 48 NXP Semiconductors TDA8932B Class-D audio amplifier (1) Where: fosc = oscillator frequency (Hz) Rosc = oscillator resistor (on pin OSCREF) ( Ω) Table 5 summarizes how to configure the TDA8932B in master or slave configuration. For device synchronization see Section 14.6 “Device synchronization”. 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: – UnderVoltage Protection (UVP) – OverVoltage Protection (OVP) – UnBalance Protection (UBP) • ElectroStatic Discharge (ESD) The reaction of the device to the different fault conditions differs per protection.
