STA510A13TR - 44V 5.5A Quad Class D Audio Power Stage
부품 번호: STA510A13TR ✓ 활성STA510A13TR 개요
A Class D audio output stage converts a PWM carrier into a filtered audio waveform at the speaker load. Compared with a linear output stage, this architecture can provide high output-current capability and high conversion efficiency, while reducing heat and power loss when the load and switching design are appropriate. The STA510A family can operate as dual-bridge, reconfigured single-bridge, or binary half-bridge mode, depending on the CONFIG connection and operating configuration.
Key features include a 44 V device rating, 5.5 A output current, a complementary DMOS output stage, and CMOS-compatible logic inputs. The device also includes thermal protection, thermal-warning output, undervoltage protection, and short-circuit protection. A minimum input and output pulse-width distortion of 150 mΩ is identified for the complementary output network, supporting compact Class D output-stage implementations with reduced conduction loss.
The STA510A13TR is intended for powered speakers, home-theater receivers, active speakers, automotive audio systems, and consumer audio equipment. Its quad half-bridge organization allows four PWM input channels to drive two full bridges or other combinations of stereo, mono, and multi-channel configurations. The CONFIG pin provides additional flexibility when a designer needs to trade channel count against output-current capability.
Designers should pay close attention to the datasheet power-supply recommendations, exposed-pad thermal path, output-filter requirements, input PWM timing, and protection behavior. The device is intended for Class D power stages rather than conventional analog voltage amplification. Keep the high-current output loop compact, provide adequate supply decoupling, and use the manufacturer reference layout to control switching noise and temperature rise.
This product page organizes the key electrical characteristics, operating configurations, protection functions, and application considerations for the STA510A13TR. It also provides comparison guidance for compatible power-stage alternatives and highlights the engineering constraints that matter when designing a robust, thermally stable Class D audio output stage.

일반적인 애플리케이션
STA510A13TR 적합 용도: 6 애플리케이션s: Stereo Home Theater Amplifier, Powered Bookshelf Speakers, Multi-Channel Active Speaker System, Automotive Audio Amplifier, Portable Bluetooth Speaker, Professional Audio Amplifier.
Stereo Home Theater Amplifier
The STA510A13TR fits a stereo Class D output stage because its quad half-bridge organization can drive two full bridges from PWM control signals. With a 44 V device rating and up to 5.5 A output-current capability, it is appropriate for powered speakers and home-theater receivers requiring high peak current. The design uses two bridge channels, an external LC output filter, and a low-impedance speaker load. The main engineering trade-off is that high-current switching stages demand careful supply decoupling, compact output loops, thermal-via placement, and EMI control around the exposed-pad structure.
추천
Powered Bookshelf Speakers
The STA510A13TR can serve as the Class D power amplifier in an active bookshelf or compact powered speaker. Its configurable half-bridge architecture supports stereo operation while its thermal-warning output can be monitored by the system controller. The 5.5 A headline current is useful for reproducing transients into low-impedance speaker loads, but the continuous rating depends on VCC, switching frequency, filter losses, and board thermal resistance. Designers should use the manufacturer reference layout and an output filter tuned for the selected switching frequency, while keeping the amplifier supply path separated from sensitive input circuitry.
추천
Multi-Channel Active Speaker System
The four half-bridge outputs of the STA510A13TR make it suitable for multi-channel active speaker architectures, including compact cinema systems and multi-zone audio products. Depending on the channel count and power strategy, the device can be configured as dual bridges or other supported arrangements. This allows a shared power-stage design to serve several speaker outputs while retaining individual PWM channels. The principal design trade-off is routing and timing: PWM signals must remain clean, output filters must be matched to the selected switching frequency, and each power section must have adequate copper and thermal-via support to maintain safe junction temperature.
추천
Automotive Audio Amplifier
The STA510A13TR is architecturally suitable for high-current automotive audio power stages because it combines a 44 V class of device with thermal, undervoltage, and short-circuit protection functions. Its quad half-bridge topology can support stereo or multi-channel speaker arrangements, while the thermal-warning signal can support system diagnostics. Qualification for a specific vehicle platform must still be confirmed from the exact STMicroelectronics automotive documentation. Critical design work includes transient suppression, load-dump protection strategy, stable low-impedance operation, vibration-related assembly controls, and an exposed-pad thermal path designed for the enclosure's heat-spreading conditions.
추천
Portable Bluetooth Speaker
A battery-powered Bluetooth speaker can use the STA510A13TR as the final Class D output stage, provided the supply, charger, and protection network are designed for its 44 V device limit. The high-current DMOS output stage supports efficient conversion of a switching waveform into speaker drive, while short-circuit and thermal protection help manage accidental load conditions. The key trade-off is that a portable enclosure has limited copper area and heat spreading, so the board must use the exposed pad, thermal vias, and low-inductance supply routing effectively. The output filter and switching layout should be validated for the chosen PWM modulator and speaker impedance.
추천
Professional Audio Amplifier
The STA510A13TR can be used in professional and commercial audio amplification where high peak output current and configurable bridge operation are important. The quad half-bridge arrangement supports multiple speaker channels or higher-current single-bridge operation when the manufacturer configuration permits it. Compared with a discrete output design, the integrated stage simplifies power-device selection and places thermal-warning, undervoltage, and short-circuit functions in one package. It still requires a careful analog input path, a stable PWM modulator, output filtering, high-current copper routing, and an enclosure strategy that removes the heat generated by the switching stage.

설계 노트
The STA510A13TR is a high-current switching power stage, so the exposed-pad region and PCB thermal path determine achievable continuous output. Use the manufacturer reference layout, place thermal vias beneath the exposed pad where recommended, and provide copper area on both sides of the board when enclosure conditions limit natural convection. Estimate the dissipated power from the supply voltage, output voltage, load current, and switching losses, then compare the resulting junction-temperature estimate with the datasheet limit before selecting the speaker impedance and output-filter topology.
Keep the high-current output loop, output transistors, supply connections, and decoupling components as compact as practical. Use very low-inductance routes for VCC and ground, place input and output capacitors close to their associated pins, and avoid sharing narrow copper paths with sensitive PWM or analog traces. The 36-pin PowerSO package requires deliberate exposed-pad soldering and via placement. Check the manufacturer land pattern and assembly requirements rather than adapting a generic SOIC footprint.
Class D switching nodes generate high dv/dt and high di/dt edges. Route the switching outputs and output-filter components with short, compact paths, and keep the filter away from microphone, sensor, and preamplifier inputs. Use a continuous ground reference under the power stage and place filtering or shielding where it is needed to control radiated emissions. The datasheet test condition of 384 kHz provides a useful reference point, but the actual switching frequency and PWM edge rate in the finished amplifier determine the final EMI layout.
