STA510FTR

Overview

The STA510FTR is a monolithic, quad half-bridge power stage manufactured by STMicroelectronics in multipower BCD technology. It operates within a supply voltage range of 10V to 40V and features a complementary DMOS output stage with an on-resistance of 150 mΩ. The device supports dual-bridge or single-bridge configurations via the CONFIG pin. In stereo mode, it delivers 100W per channel into 6Ω loads at 36V with 10% THD. In single BTL configuration, it provides 200W into a 3Ω load under identical conditions. It includes thermal protection, undervoltage protection, and CMOS-compatible logic inputs.

Feature Summary

• Configurable bridge topology allowing operation as dual-bridge, single-bridge with double current capability, or half-bridge modes.
• Integrated thermal protection and warning output for enhanced system reliability.
• Fully compatible with FFX driver devices for high-efficiency digital amplification.
• No specific power-on or power-off sequence required for operation.

Applications

• Stereo all-digital high-efficiency amplifier output stages
• Automotive audio systems requiring robust power delivery
• High-power single-bridge amplifier configurations

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeits. Confirm RoHS3 compliance and REACH status prior to integration. Ensure the package matches the PowerSSO-36 EPU specification. Check for obsolescence notices as the part may be discontinued. Validate thermal management requirements against the datasheet limits.

Selection Notes

Select this component when designing high-power digital audio amplifiers requiring configurable bridge topologies. It is suitable for applications needing up to 200W output in mono mode or 200W total in stereo mode. Consider its compatibility with FFX drivers and CMOS logic interfaces. Evaluate thermal dissipation needs given the 150mΩ Rds(on) and operating temperature range.

Part Context

The STA510FTR belongs to the STA510 family of power stages from STMicroelectronics. It is designed for high-efficiency audio applications using multipower BCD technology. The 'TR' suffix typically indicates tape and reel packaging, though official documentation should be consulted for specific handling instructions. It serves as a key component in modern digital amplifier designs.
