Part Number: Hi TI experts,
I want to use load switch TPS22914 to direct continuous current from power supply to two loops. The design circuit is as attached. I have a few concern regarding it:
1) Currents have to be bi-directional (some value between…
Part Number: TPS22914 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Dear Sir or Madam,
I am doing the operation simulation of TPS22914C with TINA-TI.
The simulation model was created by downloading snvm667.zip on the…
Hi Andy,
Welcome to e2e!
It is not recommended to rely on the body diode to conduct a systematic, purposeful current, as the body diode limits are not guaranteed by the data sheet.
1. The TPS22916 reverse current blocking function activates when the current…
Part Number: TPS22915 Other Parts Discussed in Thread: TPS22914
Dear team
Customer ask us one more question.
Do the TPS22914 and TPS22915 use the same Die? Or is there a difference in Die between TPS22914 and TPS22915?
Thanks
Hi Hirashima-san,
The difference between 914 and 915 is the presence of QOD in the TPS22915 device and so they are not exactly identical. This means that when TPS22914 is disabled, there will be no quick output discharge to pull down the output rail…
Hi Tony,
I am not an expert for selecting the switch that would best suit your expected load however is a good part to start with TPS22914. TUSB4041I does not require a specific power switch.
HI Naoki-san,
I am not sure what the output voltage is supposed to be but if it is 3.3V, when the TLV742P is disabled, it would be actively sinking ~27.5mA. Based on the R DSON of the TPS22914 (38mOhm), this alone would account for a ~1.9mV rise.
What…
Part Number: BQ24041 Other Parts Discussed in Thread: BQ24040 , TPS22914 Dear TI-Team,
here:
Bill stated that PG can be connected to EN with a pull up... why would we need a pull up (given there's no external host)?
If we actually need a pull up,…
I suspect the system load connected to battery will start to operate (try to operate) at about 2.8V. The circuit has some hysteresis, on about 2.8V and off about 2.5V. The 2.5V may be controlled by the PCM. The system starting at 2.8V then loads battery…
