STA50613TR - 40V 4A Quad Class-D Half-Bridge | STMicroelectronics
MPN: STA50613TR ✓ نشطSTA50613TR نظرة عامة
An audio power amplifier converts low-level input signals into a current and voltage swing capable of driving loudspeakers efficiently. Class-D topology switches the output stage at high frequency, reducing conduction losses compared with linear amplifiers. The STA50613TR provides four half-bridge outputs, allowing mono differential operation from two channels or stereo operation across four outputs when configured by the host system.
The quad half-bridge arrangement is useful in compact consumer-audio and automotive-style subsystems where multiple powered speakers, soundbars, or multimedia enclosures share one power-amplifier device. Logic-level control reduces the need for external driver transistors. The 200 mOhm output-stage figure and 40 V maximum supply support headroom for common battery and automotive-derived power rails, while the package exposes a large thermal slug for heat removal.
Protection features are essential in speaker systems where wiring faults, stalled voice coils, or sustained full-scale output can overload the amplifier. Thermal warning and shutdown provide escalating thermal management, and short-circuit protection limits damage during a speaker-line fault. Undervoltage protection prevents unintended output activity when the supply rail is too low for reliable operation.
STA50613TR is supplied in tape-and-reel packaging with a temperature-grade suffix reserved for industrial temperature-range production. Designers should confirm the complete pin description, exposed-slug connection, output configuration, and recommended output-filter network in the manufacturer datasheet before layout release.
This page combines the device electrical envelope, application guidance, package details, and practical integration notes to accelerate design review. It also identifies where the same-footprint qualification must be checked against a specific candidate rather than assumed from a shared package family.

التطبيقات النموذجية
STA50613TR مناسب لـ 6 التطبيقs: Compact Stereo Speaker Amplifier, High-Power Mono Speaker Driver, Soundbar and Multimedia Speaker System, Automotive Audio Subsystem, Active Speaker Network, Portable Powered Speaker.
Compact Stereo Speaker Amplifier
The STA50613TR fits compact stereo speaker modules because its four DMOS half-bridges can support a two-channel Class-D output stage from one IC, while the 36-pin PowerSO-36 package limits the number of external power devices. Each half-bridge is rated for 4 A under the stated operating conditions. A practical design assigns two outputs to each stereo channel, follows the manufacturer filter network, and places the exposed slug over a continuous thermal plane. Compared with a discrete output stage, the integrated approach reduces board area and external driver count, although sustained output still requires careful copper-area and thermal-limit verification.

High-Power Mono Speaker Driver
A mono implementation can use the STA50613TR half-bridge outputs in a differential arrangement to drive a single low-impedance speaker efficiently. The 4 A half-bridge current capability and Class-D topology suit applications where analog linear amplifiers would dissipate more power at the same output level. The design must account for inductor and capacitor selection in the recommended output-filter network, as well as the average and peak current required by the speaker impedance. The exposed PowerSO slug should be tied directly to a multilayer thermal plane so that output-stage losses can leave the package without exceeding its thermal limits.
موصى به
Soundbar and Multimedia Speaker System
The STA50613TR is appropriate for soundbar-style electronics that require several amplified outputs in a constrained enclosure. Four integrated half-bridges allow a stereo or mixed mono and stereo architecture, while CMOS-compatible control simplifies interfacing with an audio codec or digital signal processor. Short-circuit protection and undervoltage protection improve robustness during cable connection and system startup. Thermal design is the main limitation in an enclosure with restricted airflow, so calculate worst-case dissipation at the maximum unclipped output and reserve copper area around the slug before the PCB layout is frozen.
موصى به
Automotive Audio Subsystem
The STA50613TR can support a 12 V battery-derived automotive audio rail within its 10 V to 36 V operating range, making it a candidate for compact vehicle speakers and infotainment amplification. Integrated undervoltage, short-circuit, thermal-warning, and thermal-shutdown functions help manage predictable automotive faults. The 40 V maximum supply provides additional nominal rail margin, but it does not replace a complete automotive load-dump or transient-protection network. Confirm the exact temperature grade and automotive qualification status, and validate conducted immunity, emissions, and reverse-battery behavior at system level.
موصى به
Active Speaker Network
In an active speaker, the STA50613TR provides the power-conversion stage behind a digital or analog crossover, allowing multiple amplifier channels to be consolidated into a single device. Its four half-bridges can serve mono bass or midrange sections and stereo channels, subject to the device's thermal and configuration limits. CMOS-compatible logic inputs simplify control from a DSP, and the integrated protections reduce external circuitry. Keep analog input routing short, follow the recommended PWM and output-filter layout, and separate sensitive signal returns from high-current output-current paths to reduce ground-related interference.
موصى به
Portable Powered Speaker
Battery-powered speakers benefit from the Class-D operating principle of the STA50613TR because its switching output stage can deliver useful speaker power with lower conduction loss than a comparable linear design. The 10 V lower operating limit must be checked against the usable voltage of the chosen battery pack and the voltage required for acceptable output power. Short-circuit protection is valuable for portable products with removable speaker cables. Choose inductor and filter values from the manufacturer guidance, account for battery impedance at peak current, and confirm that the PCB can dissipate the worst-case loss without sustained thermal shutdown.

ملاحظات التصميم
Treat the PowerSO slug as the primary thermal path. Use the manufacturer land pattern and connect the slug to a multilayer PCB ground plane with uninterrupted copper beneath the package. Estimated: with a supply of 24 V, an 8 Ohm load, and 4 A half-bridge current, one output stage would ideally dissipate 32 W before accounting for switching or conduction loss, so continuous full-current operation requires thermal validation rather than reliance on package capacity alone.
Place the output inductors and capacitors close to their associated half-bridge outputs, and route the high-current output paths over continuous copper rather than through thin traces. Keep the PWM and input-control traces away from output-current loops. Follow the manufacturer reference layout for the exposed slug, input decoupling, and filter placement, since changing filter-component positions can increase switching noise and reduce damping.
Do not treat the 4 A output rating as a guaranteed continuous power capability at every load impedance or temperature. Confirm minimum operating voltage, maximum supply voltage, output current limits, thermal shutdown behavior, and recommended load impedance in the manufacturer datasheet. Also verify that the host system disables the amplifier during power transitions and that the thermal-warning signal is monitored instead of ignored.
Class-D output stages generate high-frequency switching energy, so EMI control begins with the recommended output filters and a compact high-current loop. Keep the audio input ground reference separate from output-current returns, and place input filtering and decoupling before long routing to the device. Validate emissions and conducted noise on the final PCB because cable shielding, speaker impedance, chassis grounding, and filter tolerances can change the result.
