IRS2052MTRPBF

Overview

The IRS2052MTRPBF is a two-channel integrated analog input Class D audio amplifier driver. It operates with a low-side fixed supply voltage (VCC/VCC2) ranging from 10 V to 15 V and supports high-side floating supply offset voltages up to 200 V. The device features selectable dead-time generation of 45, 65, 85, or 105 ns. Typical output currents are 0.5 A source and 0.6 A sink. It includes an internal clock oscillator, clipping detection, and thermal protection.

Feature Summary

• Integrates two channels of high-voltage Class D audio amplifier drivers with PWM modulators
• Features versatile protection control enabling latched, non-latched, or host-controlled shutdown functions
• Includes on-chip thermal shutdown with warning and external thermal sensor input capability
• Provides programmable over-current protection and selectable dead-time generation

Applications

• Two-channel Class D audio amplifier systems
• High-performance audio applications requiring half-bridge topology
• Consumer audio equipment utilizing MOSFET power stages

Procurement Notes

Verify the component matches the MLPQ48 package dimensions and pinout configuration before integration. Confirm that the operating conditions remain within the specified absolute maximum ratings for VCC and floating supply voltages. Ensure proper thermal management is implemented given the junction temperature limits and power dissipation characteristics defined in the datasheet.

Selection Notes

Select this component for designs requiring a complete two-channel digital audio driver solution. It is suitable for applications needing integrated protection features such as over-current and thermal shutdown. Consider the available selectable dead-time options to optimize switching performance and minimize cross-conduction risks in the power stage design.
