יישומים טיפוסיים
IRS20955STRPBF מתאים עבור 6 יישוםs: Class D stereo audio amplifier, Portable powered speaker, Multichannel home audio amplifier, Automotive audio amplifier, Industrial audio control amplifier, Professional audio output stage.
Class D stereo audio amplifier
IRS20955STRPBF fits a two-channel Class D audio amplifier because the verified family description identifies it as a 120 W x 2-channel driver. Its floating PWM input supports implementation with the appropriate external half-bridge power stage, while programmable bidirectional over-current protection with self-reset adds a useful protection function near the output transistors. The 16-pin SOIC-16 package is suitable for compact audio equipment. Exact gate-drive timing, dead time, current thresholds, and external MOSFET selection must come from the manufacturer datasheet and application circuit before production use.
מומלץ
Portable powered speaker
IRS20955STRPBF can serve as the gate-driver control device in a portable speaker design requiring two amplified channels. The verified operating-temperature range of -40 C to +125 C gives the device broad industrial temperature capability, while its 2-channel organization simplifies control of left and right outputs. The floating PWM input is useful when the amplifier architecture permits external gate-drive circuitry. Designers should account for supply limitations, external MOSFET dissipation, copper heat spreading, and the verified 1.2 A output listing in the final power-stage design.
מומלץ
Multichannel home audio amplifier
IRS20955STRPBF is appropriate for multichannel home-audio power stages that use two independent Class D outputs per device. Its verified two-channel architecture permits multiple packages to drive left, right, center, and surround channels, while the programmable preset and bidirectional over-current functions provide configurable output-stage behavior. The SOIC-16 package simplifies assembly relative to larger power packages, but it does not dissipate the power-transistor losses itself. Keep MOSFETs, gate drivers, and heat sinks thermally separate from the logic circuitry.
מומלץ
Automotive audio amplifier
IRS20955STRPBF can be evaluated for automotive audio systems because a verified component listing identifies the temperature grade as automotive and specifies operation from -40 C to +125 C. Its two-channel driver arrangement and programmable over-current protection are relevant to vehicle audio power stages, where fault handling and wide temperature operation are important. However, the retrieved data does not explicitly state AEC-Q100 qualification, so automotive production use requires obtaining the current Infineon qualification statement and confirming all AEC-Q100 requirements.
מומלץ
Industrial audio control amplifier
IRS20955STRPBF can support industrial audio equipment that requires dual PWM-driven outputs and integrated protection logic. The verified operating range of -40 C to +125 C supports designs exposed to a broad industrial ambient range, and the programmable bidirectional over-current protection with self-reset is useful for controlled output-stage recovery after a fault. The SOIC-16 device should be paired with suitably rated external power transistors and an appropriate thermal strategy. Industrial qualification status beyond the listed temperature range remains [DATA_NEEDED].
מומלץ
Professional audio output stage
IRS20955STRPBF is suitable for professional audio output stages built around external MOSFET half-bridges, particularly where two-channel control and programmable protection simplify the driver architecture. The verified IRS20955 family rating of 120 W x 2 channels indicates the intended class of power-amplifier application, while the floating PWM input provides a defined control interface for the external stage. Validate total harmonic distortion, output-current margin, protection timing, and thermal performance in the complete amplifier because those system-level results are not included in the retrieved snippets.

הערות תכנון
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.
מידע על תאימות
RoHS compliance is stated in the verified technical listing. A component listing identifies the temperature grade as automotive, but explicit AEC-Q100 qualification was not present in the supplied data.
