Overview
The STA501A13TR is a monolithic dual half-bridge stage in Multipower BCD Technology. It serves as the output stage for mono All-Digital High Efficiency (DDX) amplifiers, delivering 50W at THD=10% with Vcc=30V on an 8Ω load. Operating voltage ranges from 10V to 40V. The device features a 200mΩ RdsON complementary DMOS output stage and CMOS compatible logic inputs. Key protections include thermal warning, under-voltage protection, and short-circuit limits up to 6A typical.
Feature Summary
- Monolithic dual half-bridge stage utilizing Multipower BCD technology
- CMOS compatible logic inputs with threshold proportional to VL pin voltage
- Integrated thermal warning output and under-voltage protection mechanisms
Applications
- Output stage for mono All-Digital High Efficiency (DDX) amplifiers
- High-efficiency audio power amplifier systems
- Digital audio processing equipment requiring low distortion
Procurement Notes
Verify component status carefully as datasheet indicates obsolete product status. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing DDX amplifier designs. Check lead times and supply chain stability due to end-of-life classification. Validate packaging specifications against current inventory requirements.
Selection Notes
Select this component for applications requiring a robust dual half-bridge driver for digital audio. Consider the 200mΩ RdsON for efficiency. Verify logic level compatibility with the controller's VL pin. Ensure thermal management meets the junction temperature requirements. Evaluate if the obsolete status aligns with long-term production needs.
Part Context
The STA501A belongs to STMicroelectronics' Multipower BCD technology family, designed for high-efficiency power stages. It complements other DDX amplifier components by providing the necessary output switching capability. The PowerSO36 package facilitates heat dissipation for continuous operation in audio applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require design modifications. Consult manufacturer archives for potential legacy alternatives.
