Part Number: TPS40170

Hello team,

Do you have any application example to achieve latch-off operation when over current is detected?

If you have it, please show it.

Best regards,

Hidekazu,

Section 7.3.4 of the TPS40170 datasheet describes the Over Current Protection mechanism. Is this what you're looking for?

Hi Sam,

No. Customer is lokking for the external application circuitry to achieve latch-off at OCP or SCP.
Do you have any idea of application circuitry to do latch off ?

Hidekazu,

Here's some literature for Over-Current Detection. That lists some good parts/circuits.
