Part Number: TPS2546-Q1 Other Parts Discussed in Thread: TPS2540 , TPS2546 We made a TPS2546 to replace the TPS2540. And the Schematic as follow:
When we use TPS2540 the portable device(Meizu note9) can be charged and transmit, the Charging current is 1.39A…
Part Number: TPS2540 We are looking at using TPS2540 in our project. Our use case scenario is
1) USB host where our product will be plugged into only supports CDP charging
2) Integrated circuits used in our product will be USB device and only supports…
Part Number: TPS2540 I have a TPS2540 charging a new USB C phone. The device reports charging slowly. Using a different charger, the device reports turbo charge, confirming the device is behaving normally. Data connection happens.
The TPS2540 configuration…
Part Number: TPS2540
Hi Team,
My customer are using TI's TPS2540 as the charging current limiting chip for the USB 3.0 interface.
The circuit is shown in the figure below.
The CTL1, CTL2, and CTL3 of the 2540 are all set high, and the 5V output…
Part Number: TPS2540 Other Parts Discussed in Thread: TPS2549 Hi,
I'm working on a project which needs to supply > 500 mA to a USB device, but also function as a dual-role OTG device. The TPS2450 works fine for host mode, but there's no way to disable…
Part Number: TPS2540 The TPS2540 datasheet shows a "Host Sense" block in the diagram on page 9, but doesn't describe its function. If the TPS2540 detects the DM_OUT and DP_OUT pins are in a device mode state, will it simply turn on the data…
Part Number: TPS2540 Other Parts Discussed in Thread: TPS2546 Im using a TPS2540 in a basic usb charger circuit, set to Dedicated charging port, auto-detect mode(CTL1, CTL2=0, CTL3=1). Current limit is set to aprox. 1.2A. It works fine, but once I try…
Part Number: TPS2540 Other Parts Discussed in Thread: TPS2547 The Current Limit Thresholds Vs. Current Limit Resistance graphs depicted on page 28 of the datasheet don't seem to reasonably match the calculation per equations (4) and (5). The graphs present…
