What are the key features of STA515WJ13TR?
- Quad half-bridge topology supporting 4-channel single-ended or 2-channel BTL speaker configurations from a single IC
- 40 V / 3 A per bridge output enabling up to 30 W per channel BTL into 4-ohm loads for home audio applications
- Integrated digital PWM control interface reducing external component count and simplifying DSP-driven audio amplifier designs
What is STA515WJ13TR used for?
The STA515WJ13TR is designed for home theater receivers, soundbars, and automotive head units requiring multi-channel Class-D amplification from a single compact IC. Its 40 V supply rating and 3 A continuous output current support mid-power speaker systems delivering up to 30 W per channel in bridged configurations. The digital input interface makes it straightforward to pair with audio DSPs or SoCs that output PWM or serial audio data streams.

Frequently Asked Questions
What output power can the STA515WJ13TR deliver into a 4-ohm speaker in BTL mode?
In bridged tied load (BTL) mode, the STA515WJ13TR can deliver approximately 25 W to 30 W per channel into a 4-ohm speaker when powered from a 40 V supply at 3 A peak bridge current. This makes it suitable for home theater satellite speakers and soundbar mid-range drivers requiring moderate output power without an external power stage.
For a 4-channel home audio amplifier board, how does the STA515WJ13TR simplify the design compared to discrete solutions?
The STA515WJ13TR integrates 4 half-bridge outputs, gate drivers, and protection circuits into one small-outline package, replacing at least 8 discrete MOSFETs plus individual gate-drive ICs that would otherwise occupy more than 10 cm² of PCB area. Its digital PWM input interface eliminates the analog input stage, reducing total BOM by roughly 20 components for a 4-channel 40 V amplifier design.
What protection features does the STA515WJ13TR include for safe operation in consumer audio products?
The STA515WJ13TR incorporates overcurrent protection at approximately 3 A, thermal shutdown activating around 150 °C junction temperature, and undervoltage lockout to prevent operation below safe supply voltage thresholds. These protections safeguard both the IC and connected 4-ohm to 8-ohm speakers against damage during fault conditions such as short-circuit output or excessive ambient temperature.
When should a designer choose STA515WJ13TR over a 2-channel Class-D amplifier IC?
Designers should choose the STA515WJ13TR when the application requires 4 independent audio channels or 2 BTL channels from a single 40 V power supply, avoiding the extra PCB space and BOM cost of two separate 2-channel devices. It is especially advantageous in soundbars or AV receivers with 4.0 or 2.1 speaker configurations where a single IC can drive all channels simultaneously within a thermal budget of 2 W to 4 W dissipation at typical listening levels.
