TDA7851L

TDA7851L 4 x 48 W MOSFET quad bridge power amplifier Datasheet − production data Features ■ ■ Multipower BCD technology High output power capability: – 4 x 48 W/4 Ω Max. – 4 x 28 W/4 Ω @ 14.4 V, 1 kHz, 10 % – 4 x 72 W/2 Ω Max. MOSFET output power stage Excellent 2 Ω driving capability Hi-Fi class distortion Low output noise Standby function Mute function Automute at min. supply voltage detection Low external component count: – Internally fixed gain (26 dB) – No external compensation – No bootstrap capacitors Protections: – Output short circuit to GND, to VS, across the load – Very inductive loads – Overrating chip temperature with soft thermal limiter – Load dump voltage – Fortuitous open GND Device summary Order code TDA7851L Package Flexiwatt 25 Packing Tube '!0'03 ■ ■ ■ ■ ■ ■ ■ ■ Flexiwatt 25 – Reversed battery – ESD Description The TDA7851L is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt25 package designed for high power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail-to-rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances. ■ Table 1.
