  RE: TPS2044B: How Current Sharing Work when OUT1 and OUT2 are Tied?

  Hi Itoh-san, As you can see in the datasheet, we only have the spec of separate channel. That's guaranteed by TI. For both channel tie together, we don't have full validation of the spec. I think for the minimum trip level. The ideal value...

  RE: TPS2044B: Higher current than the limit (500mA) when USB device plugged

  Hi Nicolas, Note that 500mA is the operating current for this switch. The current limit (Ios) is 1A typical. While the Ios current limit for this device is 1A, the current must hit the Ioc trip point first before the switch will regulate at Ios. If...

  RE: TPS2044B current limiting value too high - 1.4A ! Why ?

  TPS2044B is rated for 500mA maximum operating loads. Ios = 1A typical and Ioc=1.5A typical. You can refer to Figure 11 for a waveform as well as an explanation of over current operation on page 18.

  RE: Questions for using TPS2054 with the TUSB2046, PCM2706 & PCM2900E

  Hi Ben, According to TPS2044B EVM schematic I would say that this device requires pull up resistors on OCx pins, 10K-Ohm should do it. You could ask this to the Power Management team as they are in charge of this device. Perhaps the USB Interface team...

  RE: WEBCAM Not detecting through USB HUB

  Thanks for reply. As you suggested im planning to replace TPS2044B with TPS2064 and also increase the capacitance from 22uF to 220uF on the Vbus line.
