TAS5414C-Q1 Behavior of the Protection Function in the Low-Low State

Sadanori Kato

Hi,

Do the cycle-by-cycle current limit(CBC) and the overcurrent shutdown(OCSD) work in the low-low state properly ?
Is our understanding correct although these protections do not work in this state ?

Best regards,

Kato-san,

When in low-low state, the output transistors are no longer switching and there is a pull down to ground. The CBC and OCSD are not longer able to measure output current since all the output FETs are off.

Hi Gregg-san,

Thank you for your prompt response.
I understood.

Best regards,
