Other Parts Discussed in Thread: TPS22994 Hi, The TPS22994 has 12 mode registers from 06h to 11h per the TPS22994 datasheet shown on pages 25 and 26. All of the mode settings are the same, namely "ENABLE CHANNEL". Since the TPS22994 cannot store register…
Other Parts Discussed in Thread: TPS22994 Hi, for the TPS22994 use with I2C, should the ONx pins be left floating or should they be tied to ground? On power up the device defaults to GPIO mode where the outputs are controlled by the ONx pins. If these…
Hi Wagner,
You are correct. If the GPIO inputs are tied to ground, then the device will power up with the outputs OFF. From the datasheet: "Each ON pin controls the state of the switch by default upon power up". I2C can then be initialized and all 4…
Part Number: TPS2054B Other Parts Discussed in Thread: TPS2044B , , TPS22993 , TPS22994 I am looking for USB Power Switches which have four channels and Continuous current (max) (A) above 0.5A and upto 1A.
The bench test you did really helps a lot ! As long as the reverse current is far below uA scale, I will be more confidential with TPS22958.
As to the 3.5uA unknown leak Current, When I measure uA current using TPS22994 ( U5 ), Channel 2 is ON, Channel…
Hi Fred,
The high side drivers that we have in our portfolio with best fit to your application would be our load switches. Unfortunately our highest channel count load switch only comes with 4 channels, the TPS22993 and TPS22994. These load switches…
Hi Amro,
I cannot comment on the Li-Ion Solar Charging Circuit, but I can help you with the Integrated PWR Switch block.
If you are trying to fan out and regulate a 5V power rail to different modules then this seems like a perfect application for…
