STA510FTR - 44V 5.5A Class-D Power Stage | STMicroelectronics
MPN: STA510FTR ✓ פעילSTA510FTR סקירה
A power half-bridge is a switchable output section that uses two complementary transistor paths to drive a speaker load efficiently. Class-D power stages are audio amplifiers in which the output transistors operate primarily in switching states, reducing conduction loss compared with linear output stages. Within the amplifier hierarchy, the STA510FTR is a quad power half-bridge IC, an audio amplifier, a linear and switching power-management IC, and an integrated-circuit output driver.
The principal device ratings are a 44 V maximum supply, a 5.5 A output-current rating, and a 10 V to 40 V operating supply range. The manufacturer identifies a single-bridge configuration in which the device can deliver 200 W into a 3 ohm load with 10% THD at 36 V. Its configuration flexibility allows two full bridges, one higher-current full bridge, or four half bridges to be implemented through appropriate output and CONFIG connections.
The STA510F family combines a CMOS-compatible logic interface with a complementary DMOS output stage. According to the manufacturer product page, the input-pin thresholds are proportional to the VL pin voltage, which supports compatible source signaling. The configuration pin is tied to VDD for single-bridge operation with doubled current capability, while other wiring supports dual-bridge and binary half-bridge configurations.
Typical uses include home-theater and multimedia speakers, powered subwoofers, compact consumer audio systems, automotive audio equipment, and industrial audio amplification. In a stereo implementation, the quad half-bridge arrangement can drive two speaker channels efficiently, while a mono bridge configuration concentrates the available output current into one higher-power channel. The exposed pad is central to thermal performance and requires careful PCB layout.
Designers should verify the complete pinout, output-current limits, thermal limits, and switching behavior in the official manufacturer datasheet before applying the device. The power-supply decoupling network, exposed-pad copper, output inductor network, speaker wiring, and thermal management must be designed together because high-current switching stages can create both voltage transients and substantial heat dissipation.
This product page consolidates verified manufacturer and distributor information, differentiates the supported bridge configurations, identifies where pinout and application details can be obtained, and explicitly separates verified electrical ratings from parameters that require confirmation. It also provides practical guidance for comparing the STA510FTR with other power-stage architectures without presenting unsupported substitutes as guaranteed drop-in replacements.

יישומים טיפוסיים
STA510FTR מתאים עבור 6 יישוםs: Home-Theater Stereo Amplification, Powered Subwoofer, Automotive Audio Output Stage, Multi-Channel Active Speaker System, Professional Audio Monitor Amplifier, Industrial Audio and Public-Address Amplifier.
Home-Theater Stereo Amplification
The STA510FTR fits a high-power stereo output stage because its four internal half bridges can be configured as two full bridges. According to the manufacturer documentation, the device supports a 10 V to 40 V supply range, CMOS-compatible logic inputs, and thermal warning and protection functions. This makes it suitable for powered speakers, compact home-theater receivers, and multimedia amplifiers requiring efficient Class-D output. The designer should preserve the recommended output-filter network and account for switching transients and layout-dependent EMI. At 36 V, the manufacturer states that single-bridge operation can deliver 200 W into 3 ohm at 10% THD, but actual continuous capability depends on the chosen topology, PCB copper, enclosure cooling, and speaker impedance.
מומלץ
Powered Subwoofer
The STA510FTR is suitable for a powered subwoofer because its quad half-bridge core can be reorganized as a single bridge with increased current capability by connecting CONFIG to VDD. The verified 44 V maximum rating, 5.5 A output-current specification, and 200 W into 3 ohm capability at 36 V with 10% THD provide a useful basis for high-output designs. A single-bridge configuration reduces the number of external series output networks compared with using separate half bridges. Engineering must still validate thermal dissipation, speaker excursion, protection behavior, and filter selection for the intended load impedance.
מומלץ
Automotive Audio Output Stage
The STA510FTR can serve as the high-power output section of an automotive audio amplifier when its electrical and thermal ratings are acceptable for the chosen vehicle architecture. Its 10 V to 40 V supply range accommodates systems in the upper portion of that range, while thermal warning and protection functions help support robust operation. The exposed PowerSSO pad and high-current switching outputs require a low-impedance supply network and substantial PCB copper. Automotive qualification, transient suppression, reverse-battery protection, load dump handling, and electromagnetic compatibility must be verified independently because those details are not provided in the verified data.
מומלץ
Multi-Channel Active Speaker System
The STA510FTR's four half bridges allow a designer to build a multi-channel active-speaker architecture without selecting four unrelated power-stage ICs. One possible allocation is four half-bridge channels driven by compatible PWM or Class-D input signals, while another is two stereo full-bridge channels. The quad topology provides a common supply, thermal structure, and control interface within one IC. System partitioning must ensure that the selected drive method matches the manufacturer's input and CONFIG requirements. Because the supplied sources do not provide the complete input truth table, designers should verify logic levels, modulation method, and bridge states in the official datasheet before finalizing the channel map.
מומלץ
Professional Audio Monitor Amplifier
The STA510FTR can form the power-output portion of a professional active monitor when its thermal and electrical limits fit the required loudspeaker drive. Its Class-D topology supports efficient conversion from a bipolar supply into speaker output, while the four-half-bridge arrangement offers flexible channel allocation for stereo or multiway systems. The verified 5.5 A current rating is useful for assessing drive capability, but output power into a specific monitor depends on supply voltage, load impedance, THD target, and cooling. A production design also needs EMI-aware power and output routing, stable filters, DC protection, and a load-fault strategy to protect both the IC and the loudspeaker.
מומלץ
Industrial Audio and Public-Address Amplifier
The STA510FTR is applicable to industrial audio and public-address power stages requiring high output current and flexible bridge configuration. Its 10 V to 40 V supply range and configurable quad half-bridge output can support mono high-power operation, stereo operation, or multiple distributed channels. The monolithic implementation reduces the number of separate output-driver packages, while integrated thermal protection and warning provide useful system status signals. Designers should plan for substantial dissipation, maintain recommended copper areas under the exposed pad, and protect the amplifier against shorted or incorrectly connected speakers. Surge, EMC, and safety requirements depend on the final installation and are not established by the supplied source data.

הערות תכנון
Treat the exposed pad as the principal thermal path. According to the verified package description, STA510FTR is supplied in a 36-pin PowerSSO-36 package with an exposed pad. Use the manufacturer land pattern and thermal-via recommendation, provide uninterrupted copper beneath the pad, and calculate worst-case dissipation from the selected bridge topology, load, supply voltage, and conduction losses. The 200 W headline output is not a substitute for a board-level thermal calculation.
Use a low-impedance, high-current supply network and place the recommended bulk and high-frequency decoupling capacitors close to the power pins and exposed pad. The device supports a 10 V to 40 V operating range and has a 44 V maximum rating. Maintain transient margin above the normal supply maximum, verify startup behavior for the chosen CONFIG state, and ensure the power source can support the switched output current without causing excessive rail droop or triggering undervoltage behavior.
Route the high-current switching outputs as short and compact as practical, keep the output-filter and speaker connections away from sensitive input and control traces, and use a continuous ground reference. Follow the official pin map and land pattern rather than inferring terminal assignments from generic Class-D designs. The supplied sources do not reproduce the full 36-pin diagram, so pin numbers, exposed-pad connections, and output-filter values must be taken directly from the official STMicroelectronics datasheet.
Class-D output edges can radiate switching noise even when conversion efficiency is high. Use the manufacturer's recommended output-filter topology and component values, minimize the area of high-dv/dt copper, and validate conducted and radiated emissions in the final enclosure. Input and logic traces should remain quiet, and the thermal-warning and protection signals should be routed away from switching nodes to prevent false triggering or noisy control behavior.
