TDA75610SEP-HLX

Overview

The TDA75610SEP-HLX is a quad bridge car radio amplifier manufactured by STMicroelectronics, utilizing Multipower BCD technology and MOSFET output stages. It delivers up to 4 x 45 W maximum power or 4 x 25 W at 14.4 V with 10% THD into 4 Ω loads. The device operates within a supply voltage range of 6 V to 18 V and features patented Class SB efficiency to reduce dissipated power under average listening conditions. It includes comprehensive I²C bus diagnostics for speaker status monitoring, low voltage operation compliance for start-stop profiles, and robust protection against misconnections.

Feature Summary

• Patented Class SB efficiency concept significantly reduces dissipated output power compared to conventional Class AB solutions.
• Complete I²C bus diagnostic array communicates the status of each speaker, including DC/AC load detection and clipping.
• Designed for robustness against various misconnections and compliant with OEM specifications for low voltage 'start-stop' battery profiles.
• Integrated flexible fault detection featuring independent short circuit protection, linear thermal shutdown, and ESD protection.

Applications

• Quad bridge car radio amplifiers
• Automotive infotainment systems requiring low voltage operation
• Vehicle audio architectures supporting start-stop battery profiles

Procurement Notes

Verify the specific ordering suffix HLX corresponds to the Flexiwatt27 vertical exposed pad package in tube packing. Confirm that the component meets RoHS compliance standards and lead-free requirements as specified in the production data documentation. Ensure compatibility with the intended PCB layout for the 27-pin surface mount configuration.

Selection Notes

Select this component for applications requiring high output power density combined with advanced digital diagnostics via the I²C interface. It is suitable for designs needing efficient thermal management through Class SB operation and resilience against automotive electrical transients. Consider the 6 V to 18 V operating range when designing for vehicles with varying battery states.

Part Context

This part belongs to the TDA75610 family of power amplifiers from STMicroelectronics, representing a compact member designed using BCD technology. It follows previous iterations like the TDA75610LV and TDA75610S-QLX, offering enhanced diagnostic capabilities and improved efficiency for modern automotive audio requirements while maintaining compatibility with established system architectures.

Replacement Considerations

Direct substitutes include the TDA75610LV and TDA75610S-QLX. Verify pinout and package compatibility before substitution, as the HLX suffix specifically denotes the Flexiwatt27 vertical exposed pad tube packaging.
