Class D – Audio Interface and
Decode
The audio functions of the CLASS_D BTL Power Output
are controlled with internal logic level timing signals from
the Audio Module. (See Audio – Class D BTL Amplifier on
page 28)
Class D – Short Circuit Protection
The CLASS_D BTL Power Output includes protection
circuitry for over-current conditions.
Setting the
SC_DISABLE to HIGH will disable Short Circuit protection.
When SC_DISABLE is set to LOW and a short circuit
occurs, all output FETS will be latched into a disabled
mode (all output FETS off). The short circuit latch is
autonomously reset by the AUDIO Module.
Class D - Application
Class D external components
The CLASS_D amplifier should have one 330uF and one
0.1uF capacitor to ground at its VDD (PVDD) pin. See
Table 178 for recommended external components.
The CLASS_D output also should have a series
connected snubber consisting of a 3.3 ohm, 0603 resistor
and a 680pF capacitor across the speaker output pins
(CLASS_D+, CLASS_D-). No other filtering is required.
