Operating from an 8 V to 18 V supply rail, it works directly off a standard automotive battery bus and tolerates the voltage excursions of a charging system without a separate regulator. ## Temperature range and thermal management for the enclosure The 27-Flexiwatt (Horizontal) package is a formed-lead through-hole design that bolts to a heatsink or chassis panel — the wide tab transfers the dissipated heat directly to the metalwork, keeping the die below the thermal shutdown threshold during sustained high-power output. Built-in short-circuit and thermal protection means the amplifier shuts itself down before the output stage or the load wiring fails — a common failure mode in automotive audio where a speaker wire chafes against the chassis. ## Active production — sourcing for the BOM line The I²C bus interface allows volume, balance, and mute control from a host microcontroller — the amplifier responds to digital commands over a two-wire serial link, eliminating the need for analog potentiometers in the signal path.","metaTitle":"STMicroelectronics TDA7563BH Class AB Audio Amp, 75W x 4","metaDescription":"STMicroelectronics TDA7563BH Class AB quad audio amplifier, 75W x 4 @ 2Ω, 8-18V supply, -55 to 150°C, 27-Flexiwatt.
