STA516B13TR

Overview

The STA516B13TR is a monolithic quad half-bridge stage in multipower BCD technology, functioning as a Class-D audio amplifier. It operates with a supply voltage range of 10V to 58V and supports output configurations for mono or stereo channels. The device delivers up to 400W into a 3-ohm load (mono) or 200W into a 6-ohm load (stereo). It features a 7.5-amp current capability and utilizes a PowerSO-36 package with an exposed pad for thermal management.

Feature Summary

• Configurable topology allowing operation as dual bridge, single bridge with double-current, or half-bridge modes via pin configuration.
• Integrated complementary DMOS output stage providing low on-resistance and CMOS-compatible logic inputs.
• Built-in protection mechanisms including thermal warning output, undervoltage protection, and short-circuit protection.

Applications

• High-power home theater systems
• Professional audio amplification equipment
• Automotive infotainment and sound systems

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the supplier provides authentic components from authorized distribution channels to mitigate counterfeiting risks.

Selection Notes

Select this component for designs requiring high power density and flexible bridge configuration options. Consider the PowerSO-36 package dimensions and thermal dissipation requirements when designing the PCB layout. Evaluate the need for external heat sinking based on the intended operating temperature range and load impedance conditions.
