STA516B13TR - 65V 7.5A Quad Half-Bridge Amplifier | ST
MPN: STA516B13TR ✓ সক্রিয়STA516B13TR সারাংশ
A power half-bridge is an audio-amplifier topology that switches current between two supply rails through two MOSFET half-bridges. Multiple half-bridges can be paired to form bridge-tied-load, or BTL, outputs. This Class D approach belongs to the power-amplifier hierarchy and uses efficient switching to reduce the amount of power dissipated in the output stage compared with a conventional linear amplifier.
The STA516B family combines four half-bridge outputs with flexible configuration. According to the manufacturer datasheet, connecting CONFIG to VDD can double the available current in a single-bridge arrangement. The device can also operate as four independent single-ended channels. This configurability allows one amplifier platform to address conventional stereo, high-power mono, and multi-channel speaker systems without changing the power-stage footprint.
The architecture supports audio systems operating from a 10 V to 58 V supply, with the device rated to 65 V. It can provide 400 W output power in a single-channel configuration and up to 220 W per channel in a stereo configuration. The PowerSO-36 slug-up package provides a substantial thermal pad intended for heat transfer through a PCB copper area or thermal interface to a heat spreader.
Typical applications include professional audio amplifiers, powered speakers, public-address systems, cinema and home-theater equipment, subwoofer amplifiers, and high-power multichannel audio. The flexible half-bridge arrangement is especially useful when one board design must support several speaker impedances or output configurations.
Layout is critical because a high-current Class D amplifier can switch tens of amperes. Keep power-loop paths compact, connect output returns to the exposed thermal pad according to the reference layout, and provide low-inductance supply decoupling. Avoid routing sensitive input signals through high-current switching areas.
This page organizes the manufacturer's electrical information, configuration options, sourcing details, comparison data, and practical design guidance into one engineering-focused reference for evaluating the STA516B13TR in new and existing Class D audio platforms.

সাধারণ ব্যবহার
STA516B13TR এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Professional Power Amplifier, Powered Speaker, Cinema Home-Theater Amplifier, Public-Address Amplifier, Subwoofer Amplifier, Multichannel Active Speaker System.
Professional Power Amplifier
The STA516B13TR fits a high-power professional audio output stage because its four Class D half-bridges can be configured for stereo BTL, mono BTL, or four single-ended channels. The manufacturer specifies up to 220 W per channel into 3 Ω to 8 Ω speakers from a 50 V supply. Its integrated 65 V power stage reduces the external component count of a discrete amplifier, while the PowerSO-36 slug-up package provides a direct thermal path through the board. Design the supply and output network for the intended impedance, and confirm continuous-power performance with the final copper area and heat-spreader arrangement.

Powered Speaker
For a powered stereo speaker, the STA516B13TR can use two paired half-bridges in BTL configuration to provide a floating speaker output without requiring a separate output coupling capacitor on each channel. Its 10 V to 58 V operating range permits use from compact consumer-style supplies to higher-power professional systems. The manufacturer identifies up to 220 W per channel into 3 Ω to 8 Ω speakers from 50 V. Place input and power grounding carefully, keep switching-current loops compact, and validate speaker protection independently so abnormal DC or low-frequency conditions cannot damage the output stage.

Cinema Home-Theater Amplifier
The STA516B13TR can support cinema receiver or powered-speaker electronics that require flexible channel allocation from one power-stage platform. Four half-bridges may be paired for two BTL channels, or configured as four single-ended outputs where the system architecture permits. The integrated 65 V Class D stage can reach 220 W per channel in stereo operation from a 50 V supply, making it relevant to high-power theater amplification. Keep sensitive preamplifier routing away from the output switching area and use the manufacturer's reference layout to control EMI, ground bounce, and supply transients around the exposed package pad.

Public-Address Amplifier
A public-address system can use the STA516B13TR as a high-output Class D stage for distributed or high-impedance speaker networks designed around the device's voltage and power capability. Its quad half-bridge arrangement offers flexibility for stereo zones, mono distribution, or multiple single-ended outputs. The 65 V maximum rating and 10 V to 58 V operating range provide headroom for qualified industrial power systems. The implementation must include suitable speaker-network attenuation, protection, grounding, and EMI filtering, while the amplifier layout must preserve the low-inductance paths required when the power stage switches high current.

Subwoofer Amplifier
The STA516B13TR's configurable bridge outputs suit a high-power monoblock subwoofer amplifier when the load and power requirements fall within the device limits. Connecting CONFIG to VDD permits the manufacturer-described single-bridge arrangement with double-current capability, while the overall package remains a compact quad half-bridge stage. The datasheet identifies 400 W single-channel output capability and operation from 10 V to 58 V. A practical design still needs regulated supply voltage, speaker protection, adequate copper for current flow, and a thermal solution sized for sustained low-frequency output rather than a short-duration laboratory load.

Multichannel Active Speaker System
The STA516B13TR can drive multiple active-speaker channels when a system benefits from local amplification and configurable output topology. Its four half-bridges can be assigned to two BTL stereo pairs or four single-ended channels, reducing the need for separate power-amplifier packages within a multichannel board. Each channel requires independent input routing and appropriate gain control, while shared power distribution must accommodate the device's 65 V rating and 7.5 A current capability. The PowerSO-36 slug-up package makes board-level heat spreading a central design task, particularly when all four channels operate simultaneously at elevated output.

ডিজাইন নোট
Treat the PowerSO-36 output stage as a high-current switching layout. Keep the supply, ground, output, and external switching paths compact so their loop inductance remains low. Follow the manufacturer footprint and reference-layout guidance for exposed-pad vias, keep sensitive input and feedback traces away from output switching nodes, and use a continuous ground reference to minimize ground bounce and radiated emissions.
The exposed slug is the primary thermal path from the power stage. Provide the PCB copper area and via pattern specified by the manufacturer, use an appropriate thermal interface if a heat spreader is installed, and fasten that spreader with controlled pressure. Validate the assembly at the intended supply voltage, speaker impedance, channel count, and continuous output because simultaneous four-channel operation can dissipate substantially more heat than a brief single-channel test.
Do not treat the 220 W stereo figure as unconditional continuous output. Maintain sufficient voltage headroom, verify the speaker impedance, configure CONFIG for the intended topology, and include speaker protection against DC, excessive current, and sustained overload. Check every orderable suffix against the required PowerSO-36 footprint and qualification conditions before releasing a production BOM.
Class D output edges can couple into nearby analog and control circuitry. Keep the switching node and output network away from input, feedback, and communication routes; use a deliberate ground partition only where the reference design supports it. Select input and feedback filtering with the switching frequency and stability requirements in mind, and verify conducted and radiated emissions on the final board because cable and enclosure details materially affect compliance.
