Hi Luck Wu,
With 130 kohms, Rilm resistor the current limit is set to 4.6A.
In case you want to set the current limit to 0.7A, please consider using TPS2595 or TPS2596.
It is not recommended to use TPS259260 for current limit values less than…
Hi Kevin,
Unfortunately we donot have an integrated eFuse which can monitor Voltage, Current and relay via I2C. We only have eFuses like TPS2595, TPS2594x with analog current monitor available.
Also, we do have hotswap controllers like LM25066 which…
Hi Kuramochi,
Can you please let us know the need for fast rise time ?
With 1uF Cout, the device has rise time of 2.05 ms (typ). Can you look at new device TPS2595?
Best Regards,

Hi Ilya,
eFuse devices provide ouput short circuit protection along with FLT/ pin to indicate a Fault event in the system.
For 28V rail you can consider using TPS2660 , TPS1663 or TPS2663 family of devices
For 12V rail, you can have a look at…
Hi Eli,
Thanks for the schematic. If there is a possibility for schematic change, please look at our newly released part TPS2595.
TPS2595 offers better current limit performance and is available in 2mm*2mm size
Best Regards,
Rakesh
Hi Deepak,
TPS25910 limits the over current and continue till it hits thermal shutdown. Can you look at new device TPS2595. It offers better current limit accuracy in a smaller 2mmx2mm package. This would be cost-effective over TPS25910
Best Regards…
Hi Praveen,
Quiescent current has to be below 100uA so TPS2595 is not proper.
Input range is 4V~9V so TPS25200 is not proper.
If you have other solution, please let me know.
Thanks.
Hi Matianfu,
TPS2595 eFuse can be good option to set current limit around 500mA. You can use it for both charging and discharging however make sure that the device is in enable state while powering Vmain from supercap so that you can avoid conduction…
Hi Ottey,
We don't have dual channel product like LT4220.
For positive rail, we have integrated solutions like TPS2595, TPS2594x, TPS25982 which can be chosen based on load current requirement.
For negative rail, LM5067 can be looked at but it has…
Hi Dmitri,
Yes, that is the expected accuracy data. However the variation will be narrow with respect to voltage and temperature variation.
Process variation determines the accuracy band and is the one we guarantee.
We have better accuracy new part…
