(1) DCP divider 2 mode is Apple 10.5w mode (D+=2.7V/D-=2.0V) and maximum charging current is 2.1A, so if want to support 2.1A, the minimum current limit must exceed 2.1A and you can refer to TPS2543 "Current-Limit Setting" section to calculate the resistor…
It seems like you need more of a charging circuit that can linearly regulate current. TPS2540 is a protection switch that can be used in charging applications but it is the portable device that regulates the charging current and not the TPS2540. The current…
How about a fixed current USB power switch like TPS2065C? Or adjustable current limit devices like TPS2553 (up to 1.7A), TPS2554 (up to 2.7A), or TPS2543 which is a power switch + USB 2.0 data (low speed) pass thru and charging?
Other Parts Discussed in Thread: TPS2051 , TPS2543 , TPS2543EVM-064 , TPS2590 , TPS2051B Hi,
Could you help to provide power switch for USB use.
The usb current is 0.5A and Rds(on) the smaller the better.
by the way ,the power switch can use for…
Other Parts Discussed in Thread: BQ24620 , TPS5450 , TPS2543 If I have two bq24620-based chargers on a PCB (each 5A, 14.4V output) sharing a single 24V switching PSU via a single PCB power connector. Would you recommend additional bulk input capacitance…
Other Parts Discussed in Thread: TPS2543 , BQ24195 Does the BQ24195 have USB 2.0 communication support in SDP/CDP like the TPS2543?
I looked around to see how the BQ24195 handles CDP/DCP in the datasheet, and I only found details about how the BQ24195 detects…
Hi Adam-san, My customer tested TPS2543EVM with Xperia5 and iPhoneXR however both results of charging current and DP/DM waveform weren't what we were expecting. The following post is my colleague's, so your further support would be appreciated. https…
