Hi Sandra Pradeep,
Thanks for your reaching out.
Our product line has one channel USB power switch which has almost the same feature with TPS2561A, like TPS2553-Q1, TPS2556-Q1, TPS2557-Q1, TPS2559-Q1. Could this product can meet customer's design requirements…
Part Number: TPS2557 Hi Team,
We would like to know about mechanism of the current limit.
We understand that If the load current reaches current limit value, this device coordinates the resistance of FET by the Driver.
Is my understanding correct?
