STA516BFTR

Overview

The STA516BFTR is a monolithic quad half-bridge audio amplifier stage manufactured by STMicroelectronics. It utilizes multipower BCD technology and operates within a supply voltage range of 10 V to 58 V. The device delivers 200 W per channel into 6 Ω loads with 10% THD at 51 V, or 400 W in single BTL configuration into 3 Ω loads at 52 V. It features a 7.5 A current capability, 4 channels, and a PowerSO-36 package with an exposed pad up. Operating temperatures range from 0°C to +90°C.

Feature Summary

• Configurable output topology allowing dual bridge, single bridge with double-current, or half-bridge binary mode operation via pin configuration.
• Complementary DMOS output stage providing low on-resistance and low input/output pulse width distortion.
• Integrated protection mechanisms including thermal warning output, thermal protection, and undervoltage protection.
• CMOS compatible logic inputs with thresholds proportional to the VL pin voltage.

Applications

• Output stage for stereo all-digital high-efficiency amplifiers
• Home theatre systems
• Active speakers
• Docking stations

Procurement Notes

Verify the specific suffix 'FTR' against official STMicroelectronics documentation to confirm reel packaging and moisture sensitivity handling requirements. Ensure the ordering part number matches the exact datasheet revision. Confirm that the PowerSO-36 package with exposed pad up meets your PCB footprint specifications. Validate that the operating temperature range aligns with your system's thermal design constraints.

Selection Notes

Select this component when designing high-power Class-D audio stages requiring configurable bridge topologies. It is suitable for applications needing up to 400 W in BTL mode or 200 W per channel. Consider its CMOS-compatible inputs and integrated thermal protections for simplified driver interface design. Ensure the power supply can support the required voltage levels for the desired output power.
