Vue d'ensemble

Description

TDA7564B is a quad-channel automotive power amplifier IC from STMicroelectronics. It’s designed for car radios and head units, powered from a 12 V automotive supply, and can drive multiple car speakers with good efficiency.
Key features (typical):
- Four amplifier channels with protection features (overcurrent, thermal, undervoltage, and short-circuit protection).
- Mute/standby control to reduce pops at power-up.
- Diagnostic feedback for fault indication.
- Flexible configuration for standard four-channel use or two higher-power bridged channels, depending on the application.
- Class-AB architecture for audio quality with reasonable efficiency suitable for automotive environments.
Common applications include car radios, multimedia/navigation systems, and compact car audio boards. Check the exact datasheet for supply voltage range, output power per channel, pinout, and protection/diagnostic details, as these can vary by variant.

Features

Here are the key features of the TDA7564B:
- 4-channel Bridge-Tied Load (BTL) car audio amplifier
- Typical output: about 11 W per channel into 4 Ω (and ~6–8 W into 8 Ω)
- Wide supply range: roughly 6–18 V DC (car battery environment)
- No output coupling capacitors required due to BTL configuration
- Mute and Standby control with pop/noise suppression on power-up
- Robust protection: per-channel overcurrent, short-circuit (to GND or to Vcc), thermal shutdown with auto-restart, undervoltage lockout
- Broad audio performance: wideband response (roughly 20 Hz–20 kHz) with low distortion
- Suitable for automotive head units and car radios
- Typical packaging used in automotive applications (e.g., Multiwatt/PowerSO-20 variants)
Note: exact power figures can vary with line/load conditions; consult the datasheet for precise conditions and recommended operating ranges.

Package

Package: Multiwatt-15 power package (through-hole).

Pinout

- Pin count: 15 pins (Multiwatt-15 package).
- Function: Four-channel car-audio power amplifier with four bridge-tied-load outputs (OUT1–OUT4) driven from four inputs (IN1–IN4); includes Vcc, GND, and standby/mute and bias/reference pins for protection and control.

Manufacturer

- Manufacturer: NXP Semiconductors N.V. (formerly Philips Semiconductors).
- What kind of company: A Dutch multinational semiconductor company that designs, manufactures, and sells integrated circuits and system solutions for automotive, security, IoT, and other markets.

Application

Typical applications: 4-channel automotive audio power amplifier ICs used in car radios/head units and in-car entertainment systems. Suitable for front/rear channel amplification in OEM cars, aftermarket car audio, and integrated dash/multimedia players. Provides bridge-tied-load (BTL) outputs for efficient speaker drive, operates from 12–14 V automotive supply, with features such as mute/standby, thermal and short-circuit protection for rugged car use.

Equivalent

TDA7564B is a 4-channel automotive power amplifier IC (BTL). There isn’t a single exact drop‑in substitute from another vendor. Closest cross‑references are:
- NXP: TDA7564 (older) and TDA7564A (updated, same family)
- Other vendors offer similar 4‑channel automotive amps (check ST, TI, ON Semi) with comparable voltage/power specs (≈14–18 V rail, ~4×15–25 W per channel), but pinouts and features may differ.
Always verify pinout, supply range, filters, and thermal specs for a true replacement.
