TDA75610S-8ZT

Overview

The TDA75610S-8ZT is a quad bridge car radio amplifier designed in BCD technology. It delivers up to 45W per channel into 4-ohm loads at 14.4V with 10% THD, and supports 2-ohm driving capability for up to 64W maximum power. The device operates on a supply voltage range of 6V to 18V. It features Class SB efficiency, full I2C bus diagnostics including DC/AC load detection, and independent front/rear soft play/mute controls. The component is housed in a PowerSO-36 package with exposed bottom pad.

Feature Summary

• Intelligent power architecture utilizing patented Class SB efficiency concept to reduce dissipated output power compared to conventional Class AB solutions.
• Comprehensive digital diagnostics array communicating speaker status via the I2C bus, including DC offset detection and clipping detector with selectable thresholds.
• Robust protection mechanisms featuring four independent short circuit protections, linear thermal shutdown with multiple warnings, and ESD protection.
• Low voltage operation compliance supporting 'start-stop' battery profiles during engine stop to assist in emission reduction.

Applications

• Automotive audio systems requiring high-efficiency quad bridge amplification
• Car radio designs compatible with low voltage start-stop battery profiles
• Vehicle infotainment systems needing integrated I2C diagnostic capabilities

Procurement Notes

Verify the specific suffix against official STMicroelectronics documentation to confirm package type and electrical characteristics. Ensure compatibility with automotive environmental standards such as AEC-Q100 if required by the design. Confirm that the I2C interface levels match the system controller specifications. Check for any recent Product Change Notifications (PCN) regarding material or assembly updates before finalizing procurement orders.

Selection Notes

Select this component when designing automotive audio applications requiring high output power with reduced thermal dissipation. The integrated I2C diagnostics simplify system monitoring and fault detection. Consider the PowerSO-36 package for surface-mount assembly needs. Verify that the 6V to 18V supply range aligns with the vehicle's electrical system, particularly during cranking and start-stop events.

Part Context

This part belongs to the TDA75610 family of automotive Class-AB audio power amplifiers. It represents an evolution in STMicroelectronics' intelligent power technology, combining MOSFET output stages with advanced digital control. The family is widely used in modern vehicle infotainment systems due to its balance of performance, efficiency, and diagnostic integration.

Replacement Considerations

The TDA75610SLV is a related variant within the same family offering similar functionality. Verify pinout and software compatibility when substituting. Other members like the TDA7569BDLVPD offer different power ratings but share the diagnostic architecture.
