IRS20955STRPBF Tóm tắt

Infineon Technologies IRS20955STRPBF is a two-channel audio line driver and peripheral driver IC designed for Class D audio power-amplifier applications. The device supports a supply voltage described as 12 V in the verified technical listing, operates from -40 C to +125 C, and is packaged in a 16-pin SOIC-16 package using the MS-012AC outline. Its verified feature set includes a floating PWM input for straightforward half-bridge implementation, programmable bidirectional over-current protection with self-reset, and programmable preset behavior. The IRS20955 family is identified as a 120 W x 2-channel Class D audio power-amplifier driver, while an alternative manufacturer listing describes the IRS20955STRPBF as a 100 V, 1.2 A, two-output high-side/low-side half-bridge driver. The device is therefore positioned between low-power control logic and the output stage of a robust audio amplifier. Its 16-pin surface-mount construction supports compact audio products while retaining the thermal and assembly characteristics expected of an SOIC package. Infineon’s IRS20955 family also appears in the verified cross-reference data as closely related to IRS20953, IRS20956, and IRS20957, with application-dependent distinctions. Because exact pin-level compatibility, electrical limits, pricing, and some package details were not supplied for every candidate or parameter in the retrieved data, those items are marked for engineering verification rather than inferred. This page combines verified distributor descriptions, datasheet references, and practical design guidance for engineers evaluating IRS20955STRPBF in audio amplifier designs.

The verified web results confirm the package and pin count but do not expose the complete numbered signal list in their snippets, so a reliable 16-entry pin map cannot be reconstructed here. Use the package drawing and pin-description pages in the datasheet PDF rather than inferring connections from neighboring IRS209xx devices.

Is IRS20955STRPBF suitable for Class D audio amplifiers?

Yes, IRS20955STRPBF is specifically suited to Class D audio power-amplifier designs. The verified family description identifies it as a 120 W x 2-channel driver, and the device provides the floating PWM input required for convenient half-bridge implementation. Its programmable bidirectional over-current protection with self-reset is also directly relevant to audio output-stage protection, although final amplifier power and fault behavior depend on external power transistors and the selected operating conditions.

What voltage and current ratings are listed for IRS20955STRPBF?

The verified component listing describes IRS20955STRPBF as a 100 V, 1.2 A, two-output high-side/low-side half-bridge driver, while another technical listing specifies a 12 V supply. These figures describe different aspects of the device and should not be interpreted as interchangeable without checking the datasheet operating tables. The complete recommended versus absolute-maximum limits are [DATA_NEEDED: absolute maximum ratings and recommended operating conditions].

Where to buy IRS20955STRPBF online?

IRS20955STRPBF can be purchased through the verified DigiKey listing for Infineon Technologies, where the part is categorized as an audio special-purpose IC and described as a two-channel, 16-SOIC audio line driver. Additional distributor pages include ETEI and other authorized or component suppliers. Live inventory and order acceptance should be confirmed during checkout because the retrieved result states that it ships today but does not provide a stable quantity or price snapshot.

What is the price of IRS20955STRPBF?

The verified search results do not expose a numeric distributor price for IRS20955STRPBF, so a factual price cannot be stated here. The DigiKey page provides live pricing and availability for the component, while the ETEI page provides ordering information. Request a quotation from the selected distributor for production quantities because pricing depends on quantity, inventory, and date. All quote references should be checked as of 2026-10-28.

What is the lead time for IRS20955STRPBF?

The verified DigiKey result says IRS20955STRPBF ships today, but it does not provide a complete lead-time schedule or a guaranteed stock quantity. Treat that wording as a current distributor indication rather than a contractual manufacturing commitment. For a production BOM, obtain written confirmation of stock, factory lead time, and allocation status directly from DigiKey or another authorized distributor as of 2026-10-28.

Is IRS20955STRPBF in stock?

IRS20955STRPBF is shown as an orderable part with a DigiKey result stating that it ships today, but no numeric inventory count is present in the verified data. The appropriate schema availability is therefore not treated as a guaranteed in-stock quantity. Confirm live inventory at checkout and obtain a supplier allocation for production orders as of 2026-10-28.

IRS20955STRPBF vs IRS20957STRPBF - which is better?

IRS20955STRPBF and IRS20957STRPBF belong to the same documented IRS20955/IRS20957 family, but the verified snippets do not provide enough parameter-level differences to state which one is universally better. The IRS20955STRPBF is identified as a 120 W x 2-channel driver with floating PWM input and programmable protection. Compare the IRS20957 output-stage configuration, current limits, fault behavior, and pin mapping in the current manufacturer datasheet before making a drop-in decision.

When should I choose IRS20955STRPBF over IRS20953?

Choose IRS20955STRPBF when the design specifically requires the verified IRS20955 features, including a floating PWM input, programmable bidirectional over-current protection with self-reset, and programmable preset behavior. The retrieved cross-reference identifies IRS20953 as a related family device, but the available data does not establish every electrical and pin-level difference. Confirm the target output-stage topology and protection thresholds in the datasheet before treating either device as an interchangeable choice.

Can IRS20957STRPBF replace IRS20955STRPBF?

IRS20957STRPBF is a related device in the documented IRS20955/IRS20957 family, but the verified results do not prove complete pin-to-pin compatibility. A valid drop-in decision requires identical SOIC-16 pin functions, compatible PWM polarity, matching current and voltage limits, and equivalent fault-response timing. Review the manufacturer pinout and comparison tables before substituting IRS20957STRPBF for IRS20955STRPBF in an existing PCB.

What can replace IRS20955STRPBF?

The verified cross-reference data lists IRS20953, IRS20956, and IRS20957 from International Rectifier as the closest related equivalents. Their suitability as drop-in replacements is conditional on the same 16-pin SOIC footprint, identical PWM and enable behavior, compatible output-stage drive levels, and matching protection thresholds. The retrieved excerpts do not establish those conditions for every candidate, so each substitution must be checked against the current family datasheet and its pinout.

What are the design considerations for IRS20955STRPBF in a half-bridge amplifier?

Use the IRS20955STRPBF floating PWM input as the control interface for the selected half-bridge output stage and configure the verified programmable bidirectional over-current protection and preset functions around the power stage. Keep the PWM and gate-drive paths short, provide adequate local decoupling, and account for the thermal limits of the external MOSFETs. The retrieved data does not include recommended capacitor values or timing thresholds, so those values must be taken from the manufacturer datasheet rather than estimated.

Is IRS20955STRPBF RoHS compliant?

Yes, the verified technical listing identifies IRS20955STRPBF as RoHS compliant. The package is a 16-pin SOIC with an MS-012AC outline, and the operating-temperature listing extends from -40 C to +125 C. RoHS compliance does not by itself establish AEC-Q100 qualification, REACH status, halogen-free status, or conflict-minerals compliance; those declarations remain [DATA_NEEDED] unless confirmed directly from the manufacturer’s current compliance documentation.

Hướng dẫn chọn lựa

Choose IRS20955STRPBF for a dual Class D output stage that specifically benefits from its floating PWM input, programmable preset function, and bidirectional over-current protection with self-reset. Its 16-pin SOIC-16 format is appropriate for compact audio products, while the verified -40 C to +125 C range supports demanding ambient environments. IRS20953, IRS20956, IRS20957, IRS20955, and IRS20955S are the closest documented alternatives, but the retrieved evidence does not provide enough parameter-level detail to claim universal equivalence. Select one of them only after comparing the exact pinout, PWM polarity, protection timing, output-current capability, and voltage limits in the current family datasheet. For automotive production, obtain explicit AEC-Q100 documentation because only the temperature grade and automotive designation are verified here.

Ghi chú thiết kế

Design the IRS20955STRPBF supply and gate-drive paths around the external MOSFET power stage rather than treating the 1.2 A output listing as a complete amplifier-current specification. Confirm the device's absolute maximum ratings, quiescent current, undervoltage behavior, and gate-drive voltage in the current manufacturer datasheet. Use the floating PWM input with suitable gate resistors and local decoupling, and verify dead time across the complete switching cycle.

Place the driver close to the external power transistors while keeping the SOIC-16 thermal path unobstructed on the PCB. Most amplifier heat is generated in the MOSFETs, so provide copper spreading, a suitable heatsink, and planned airflow according to the actual output power. Use the manufacturer thermal data to calculate junction temperature; the retrieved excerpts do not provide a verified SOA curve or junction-to-ambient resistance.

Route PWM and gate-drive traces as short, impedance-controlled paths, and keep switching-node copper away from the floating PWM input and programming networks. Use a solid ground plane, place input and bypass capacitors at their associated pins, and provide a low-impedance return for each half-bridge. Verify dead time, ringing, channel crosstalk, and output distortion with oscilloscope measurements before production release.

Do not infer that the family relationship alone guarantees a drop-in substitution. Verify the SOIC-16 pin functions, PWM polarity, fault timing, current thresholds, voltage ratings, and external component values for each IRS20953, IRS20956, IRS20957, IRS20955, or IRS20955S candidate. Also confirm whether the design requires the verified programmable bidirectional over-current protection with self-reset behavior.
