Part Number: TPS22912C
Hi
Now we are considering the following charger system.
If the charger is connected, Li-ion battery would be charged. (Figure 1)
Then, when the charger is disconnected VOUT voltage (voltage of Li-ion) appears at VIN of…
Other Parts Discussed in Thread: TPS22912C Dear support member,
My customer used TPS22912C.
TPS22912C include Reverse Current Protection.
What is the circuit configuration of Reverse Current Protection? Could you teach equivalent circuit?
VRCP include comparator…
Other Parts Discussed in Thread: TPS22912C Hello,
When using TPS22912C, does a 3 Meg resistor from ON to GND provide sufficient pull-down strength? Or should a lower resistance value be used (and if so, what is the maximum acceptable value)?
Thanks,
J…
Other Parts Discussed in Thread: TPS22912C Hello,
Aside from the addition of quick output discharge and a slightly faster rise time, are there any other notable differences between TPS22912C and TPS22913C?
Thanks,

Part Number: TPS22910A Other Parts Discussed in Thread: TPS22912C I am trying to use the TPS22910A in a voltage mux application where on voltage may not be present.
1. Is there potential to damage the device in the Vin=0 Vout =2.5V case?
2. Will the UVLO…
Part Number: LM66100 Other Parts Discussed in Thread: TPS22918 , TPS2121 , TPS2120 , TPS2113A , TPS2115A , TPS22912C HI,
I need to switch between 2x 5V sources at 1A each ( not a power sharing application). Looking at all the ICs available, I found that the…
Hi Alek,
Our first order of TPS22910A-EVM was acting as enable high. Component stuffing option was different per datasheet, and the unit was acting as enable high instead of enable low eventually the board became unresponsive (Vin = 5V, nEN = High/Low…
Hi Zhengquan,
What is the voltage and current levels in this application? What kind of UVLO control is needed?
Off the top of my head I would suggest taking a look at TPS22953 and TPS22954 which implement a UVLO similar to TPS22810.
You can also look…
Hi Arthur,
the TPS22912C is only 2A, we need 4.5A and up. I think we will need an external comparator with hysteresis + load switch.
Best Regards,
David.
Part Number: TPS22963C Other Parts Discussed in Thread: TPS22916 , TPS22912C , TPS22953 Hi Sir
Our schematic is below
When we supply 5V to ACIN ,we can measure a 1V voltage on 5V_ADP1
On pin is 0ohm to GND
How could I solve this issue ?
