TPA3244EVM Clip Overtemperature and Fault Indicators
The TPA3244EVM is equipped with LED indicators that illuminate when the FAULT or CLIP_OTW pin
goes low. See
and the TPA3244 data sheet (
) for more details.

TPA3244EVM LC Filter
The TPA3244EVM is equipped 10-µH inductors and 1-µF capacitors for the output LC filter. These
components are setup as a Type-2 filter shown in
, since this allows the support of both BTL and
SE output configurations required for the EVM.
