■ ESD
Flexiwatt25
Protections:
■ Output short circuit to gnd, to V_S, across the
load
■ Very inductive loads
■ Overrating chip temperature with soft thermal
limiter
■ Load dump voltage
■ Fortuitous open GND
■ Reversed battery
Description
The TDA7384A is a new technology class AB
audio power amplifier in Flexiwatt 27 package
designed for high end car radio applications.
Thanks to the fully complementary PNP/NPN
output configuration the TDA7384A allows a rail to
rail output voltage swing with no need of bootstrap
capacitors. The extremely reduced components
count allows very compact sets.
