SN6505A: About current sensing

Part Number: SN6505A

Hi,

Could you tell me about SN6505A internal current sensing?
Is current detection of SN6505A pulse by pulse type?
Or restart type?

Best Regards,
Yusuke

    Hi Yusuke-san,

    The current limit in the SN6505 operates on a cycle by cycle basis, and the current on D1 and D2 is clamped to ~1.75A. This does not involve turning the device or internal FETs off or causing the current to = 0.

    Is this a helpful answer? Please let me know in your response!


    Thank you,
