IRS2092SPBF - Protected 100V Class-D Driver | Infineon
MPN： IRS2092SPBF ✗ 停產IRS2092SPBF 概覽
A Class-D audio amplifier driver is a specialized gate-drive IC that converts an analog audio input into high-frequency PWM signals for external half-bridge MOSFETs. The IRS2092SPBF belongs to the audio-amplifier-driver hierarchy, combining modulator, gate-driver, and protection functions in one controller. Unlike a finished audio output amplifier, it requires external power transistors, gate resistors, passive networks, and an appropriate output filter.
The verified product information identifies the device as a mono, analog-input Class-D amplifier with digital audio amplification behavior. Its stated 100 V voltage class, 500 ns timing value, and 800 kHz associated switching specification are useful for evaluating gate-drive bandwidth and system architecture. The integrated protection is intended to improve robustness in external-MOSFET audio power stages, although exact protection thresholds and conditions must be confirmed from the manufacturer datasheet.
Typical uses include compact stereo or multichannel audio systems, powered speakers, automotive audio infrastructure, home-theater equipment, and industrial audio products. The device is most appropriate when the designer wants controller-level flexibility with discrete MOSFET selection rather than a fixed integrated power amplifier. The 16-SOIC package also makes it compatible with conventional surface-mount PCB assembly processes.
A critical design consideration is that controller ratings do not determine the final speaker power. Output power depends on external MOSFET selection, supply voltage, modulation strategy, output filter, transformer or speaker impedance, and thermal design. Use the manufacturer datasheet and application circuits for gate-drive timing, dead-time behavior, fault handling, bootstrap or high-side supply requirements, and PCB layout.
This product record consolidates the verified manufacturer and distributor descriptions with practical application guidance and explicitly identifies parameters that require confirmation before layout or production release.

典型應用
IRS2092SPBF 適用於 6 應用s: Powered Speaker Class-D Amplifier, Home-Theater Audio Power Stage, Automotive Audio Amplifier, Multichannel Audio Amplifier, Industrial Audio Amplifier, External-MOSFET Audio Output Design.
Powered Speaker Class-D Amplifier
The IRS2092SPBF is suitable for a powered-speaker design that needs a mono Class-D power stage with external MOSFET selection. Its integrated PWM modulator and protection allow the controller to generate the drive signals for two external switching devices, while the designer selects the MOSFETs for the target speaker impedance, supply voltage, and output power. The 100 V stated rating provides a useful high-voltage design context, but actual allowable supply and output power must be verified in the manufacturer datasheet. A conventional output filter, gate resistors, passive network, and thermal layout are still required.
推薦
Home-Theater Audio Power Stage
In a home-theater receiver or powered speaker, IRS2092SPBF can serve as the controller for a discrete Class-D output channel. The architecture is useful when designers want separate MOSFET selection, thermal scaling, and protection strategy rather than a fixed integrated audio amplifier. The controller’s 500 ns gate-drive timing and 800 kHz associated switching specification should be included in EMI, output-filter, and thermal reviews. The final design must follow Infineon’s reference topology and verify all protection behavior under speaker, supply, and fault conditions.
推薦
Automotive Audio Amplifier
IRS2092SPBF may be considered for automotive audio infrastructure when the system requires a discrete Class-D output stage and the exact orderable part meets the vehicle’s qualification requirements. The supplied Partstack result identifies an automotive temperature grade, but the verified data does not provide a formal AEC-Q100 qualification statement or full temperature limits. Engineers must therefore confirm the manufacturer’s automotive qualification, environmental test results, load-dump behavior, and protection response before using it in a safety- or mission-relevant vehicle platform.
推薦
Multichannel Audio Amplifier
A multichannel amplifier can use repeated IRS2092SPBF channels, with each channel driving its own external MOSFET pair and output network. This arrangement separates controller selection from power-device selection, allowing the design to scale channel power or use different thermal budgets per channel. The main design challenges are synchronized modulation, inter-channel noise, grounding, supply decoupling, fault isolation, and heat removal from the external MOSFETs. The supplied data confirms a one-channel device, so channel count must be implemented at the board level rather than assumed inside the IC.
推薦
Industrial Audio Amplifier
IRS2092SPBF can support industrial audio products where a robust, discrete Class-D stage is preferred over an integrated power amplifier. Its controller-plus-protection approach leaves MOSFET selection to the system designer, which can accommodate long speaker cables, higher supply rails, or specialized thermal constraints. However, cable length, inductive loading, EMI, ground loops, and fault behavior require careful validation. The verified data does not provide industrial certification, operating-temperature limits, or EMC test results, so those claims must not be inferred from the application itself.
推薦
External-MOSFET Audio Output Design
The IRS2092SPBF is specifically suited to an external-MOSFET audio output because it is described as a Class-D driver with a PWM modulator and protection. Designers can choose external devices based on breakdown voltage, RDS(on), gate charge, switching loss, and thermal resistance, then optimize the power stage independently of the controller. This flexibility is valuable for higher-power or customized speaker outputs, but it increases design responsibility: gate-drive impedance, dead time, DC bias, output filtering, shoot-through prevention, and fault recovery must be verified against the exact datasheet and reference circuit.

主要差異化特點

- High-voltage device class (對比IRS2092S)
設計說明
Treat the IRS2092SPBF as a controller, not the complete speaker amplifier. Select two external MOSFETs using the verified 100 V class as context, then check the actual datasheet supply limits, gate-drive requirements, switching loss, and thermal capability. The final audio power depends on MOSFET RDS(on), supply voltage, modulation, output filtering, and speaker load rather than on the controller MPN alone.
Keep the high-current switching loop compact and place the controller, gate resistors, external MOSFETs, and power-return paths so that switching-node energy is not forced through sensitive analog traces. Follow the Infineon application-circuit layout rather than improvising a generic audio layout. The verified data does not provide trace widths, creepage distances, or component values, so use the manufacturer guidance for final dimensions.
Most Class-D heat may be dissipated in the external MOSFETs rather than in the IRS2092SPBF. Calculate conduction and switching loss from the actual supply, load, MOSFET parameters, modulation, and switching conditions, then provide copper, thermal vias, and package-appropriate cooling where required. Do not use the controller’s 100 V rating as a thermal rating or assume the SOIC package limits MOSFET dissipation.
Do not substitute a related MPN solely because it is labeled SOIC-16. Verify every pin function, supply range, timing parameter, protection threshold, fault response, and thermal grade against the exact datasheet. The supplied cross-reference supports IRS2092STRPBF as a package-compatible candidate, but it does not provide enough numerical data to prove complete electrical equivalence.
合規資訊
The verified product and distributor listings do not explicitly provide compliance declarations. A Partstack snippet identifies an automotive temperature grade, but this is not treated as formal AEC-Q100 qualification. Verify the exact orderable MPN with Infineon environmental and compliance documentation.
