Part Number: TPS2556 Hi
My customer evaluate TPS2556.
They use 174kΩ as RLIM.
Are there the data about current limit value vs temperature characteristic?
Best regards,

Hi all Would you mind if we ask TPS2556? If it is possible, could you give us the type of current sensing? What is used for current sensing?Hall sensing or shunt resistor? As the background of this question, our customer would like to…
Part Number: TPS2556 Hi team,
The customer application is EN pin is forced by 3.3V during IN is 0V, the customer want to confirm not to occur leakage current from EN pin to IN pin.
Does leak currents occur below the following conditions?
EN# = 3.3V…
Part Number: TPS2556 Customer is using TPS2556 with a 49.9K current limit programming resistor, thus Ios maximum should be about 2.5A. Customer would like to know expected package and/or lead temperature when the die is near its 135C thermal shutdown…
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…

Hi Sir,
My customer met a output unstable issue as below:
CH1 is USB_PWR(5V)
CH2 is EN pin
They have 3 load on this path: Ethernet IC, USB HUB and Wifi IC.
GPIO of SoC (EN pin) could work normally if we cut…
