TAS5719: TAS5719 Headphone out Short Protection

Akihisa Tamazaki

Part Number: TAS5719

Hello team,

The customer had a question about Short Protection at HP_PWML/R pins.

I do not believe that TAS5719 has over current protection function, however TAS5719 does not break even if HP_PWML/R pins connected to GND (short condition) by pin jack, because TAS5719 output power is too small.

Is it correct? I would like to confirm about short condition between HP_PWML/R pins and GND.

Your advise would be so appreciated.

Best Regards,

Hi Akihisa,

This is correct. There is no short circuit protection for the HP PWM pins.
