NXP Semiconductors
TDA8594
I²C-bus controlled 4 × 50 W power amplifier
I Fully programmable diagnostic levels can be set:
N Programmable clip detection: 2 %, 5 % or 10 %
N Programmable thermal pre-warning
I Selectable information on the DIAG and STB pins:
N The STB pin can be programmed/multiplexed with second clip detection
N Clip information of each channel can be directed separately to the DIAG pin or the
STB pin
N Independent enabling of thermal, clip or load fault detection (short across or to V_P
or to ground) on DIAG pin
