[ TPS2549-Q1 ] Usage as Load Switch (No USB Charging Port Controller)
Hi,
My customer is supposed to use TPS2549-Q1 for two different type of USB port.
#1: USB port with BC1.2 and load switch function
#2: USB port with load switch function (standard port with 500mA capability)
For those two different ports, customer still would like to use TPS2549-Q1.
For #2, can you help me to clarify followings?
Q1: How CTL should be?
As my understanding, high-side switch and charging controll block are separated, means operate independently.
So if these CTLx pins are left open, the load switch should work as expected. Correct?
Q2: Data path
Do we need to have data path input and output for this usage?
As above, no charging port controll function is required, I guess these can be left open (i.e. bypassed via external sgnal path.)
Q3: Any concerns inveolved?
If you have any concerns for this usage, please let me know.
Thank you for your support in advance.
Regards,
Ken
