Overview
The AN5279 is a monolithic integrated circuit designed as a mono channel SEPP audio power amplifier for TV applications. It delivers 5.0 W output at 19 V into an 8 Ω load with 10% THD, and up to 7.0 W at 22 V. The operating voltage range spans 10 V to 24 V. Key electrical characteristics include a quiescent current of 25 mA typ., voltage gain of 34 dB typ., and ripple rejection ratio of 55 dB typ. Total harmonic distortion is specified at 0.2% typ. The device operates within an ambient temperature range of -25 °C to +75 °C.
Feature Summary
- Integrates built-in muting, stand-by, and protection circuits including load-short, thermal, over-voltage, and over-current safeguards.
- Requires minimal external components by eliminating the need for Boucherot cells, bootstrap capacitors, and negative feedback capacitors.
- Provides high ripple rejection capability of 55 dB typical.
Applications
- TV
Procurement Notes
Verify component status before design implementation. The datasheet explicitly identifies the AN5279 as Maintenance/Discontinued. This classification encompasses planned maintenance, active maintenance, planned discontinued, and fully discontinued stages. Consult official Panasonic semiconductor lifecycle resources for precise availability and end-of-life information prior to procurement.
Selection Notes
Select this component for single-channel audio amplification in television systems requiring a supply voltage between 10 V and 24 V. Ensure adequate thermal management using an external heatsink, as the package requires chassis mounting for optimal power dissipation. Verify that the application does not exceed absolute maximum ratings, particularly regarding supply voltage transients and junction temperature limits during operation.
Part Context
The AN5279 belongs to the Panasonic ICs for TV product line. It utilizes the HSIP009-P-0000E package. The datasheet publication date is June 2006. The document identifier is SDB00008BEB. The manufacturer is Panasonic Electronic Components.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation.
FAQ
What is the function of Pin 9?
Pin 9 is the Standby control pin. Applying 0 V activates standby mode, while applying VCC enables operational mode.
How is the Mute function controlled?
Mute is controlled via Pin 6. A logic high of 5 V turns mute on, while 0 V turns mute off.
What happens if the temperature protection circuit activates?
The protection circuit operates at a junction temperature around 150 °C. If the temperature decreases, the circuit automatically deactivates and normal operation resumes.
