The thermal protection shuts down the output before the die exceeds safe junction temperature — useful if the speaker impedance dips or airflow stalls. Shutdown pin lets a microcontroller or GPIO hold the amp in low-power idle between audio bursts, saving battery in duty-cycled applications.
No last-time-buy or end-of-life notice is on record.
Yes. The 2.5V to 5.5V supply range matches single-cell Li-ion, and the shutdown pin allows low-power idle between audio bursts, making it a fit for portable speakers, headsets, and handheld radios.
