E-TDA7385 STMicroelectronics

TDA7385 4 x 42 W quad bridge car radio amplifier Datasheet production data Features High output power capability: 4 x 42 W / 4 max. 4 x 23 W / 4 14.4 V, 1 kHz, 10 % Clipping detector Low distortion 0 03 Low output noise Flexiwatt25 Standby function Mute function Automute at min. supply voltage detection Diagnostics facility for: Clipping Reversed battery Out to GND short ESD Out to V short S Thermal shutdown Description Low external component count: Internally fixed gain (26 dB) The TDA7385 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed No external compensation for high end car radio applications. No bootstrap capacitors Based on a fully complementary PNP/NPN Protections: configuration, the TDA7385 allows a rail to rail Output short circuit to GND, to V , across S output voltage swing with no need of bootstrap the load capacitors. The extremely reduced boundary Very inductive loads components count allows very compact sets. Overrating chip temperature with soft The on-board clipping detector simplifies gain thermal limiter compression operations. The fault diagnostics Load dump voltage makes it possible to detect mistakes during car- Fortuitous open GND radio assembly and wiring in the car. Table 1.
