I'm designing a laptop that has the unique feature of using LiFePO4 batteries (8x 18650 cells in series). To charge them, I chose the LTC4162-F charger coupled with a LTC6803-4 cell stack monitor. Both are watched/controlled by a NXP LPC11U24 MCU…
We have a request for LiFePO4 Step-Down Battery Charger.
For 4S1P application,
Vin : 9V~36V
18V->LTC4162-F->Charge LiFePO4 and backup with PowerPath and I2C Telemetry
Do we have LTC4162-F EVB or Reference Circuits inclu…
This is a duplicate question. The answer may be found here:
I actually think your components sound fine since you were charging up to 8A. At least, so far, I don't have a reason to believe there is a problem with your components.
This sounds like a battery hot-swapping and inrush issue, which…
Yes, LTC4162 is probably the best choice for your application if your desired charge current is 3.2A or less. Otherwise, you might consider LTC4015.
The suffix to the LTC4162 part number denotes the battery chemistry type that it supports…
Hi, For LTC4162-L (Lithium Ion) version in datasheet its not clear which register are fixed in fix version ( LTC4162-L42 ).Please tell me register address which can not be modified/write in fix version.
Yes, it will work with a LiPo battery. Refer to the -L datasheet for that. The LiFePO4 variants are detailed in the -F datasheet.
As for protection, it depends what you mean. One thing that the LTC4162 does not do is low-battery disconnection from the…
The folders refer to each LTC4162 variant.
If you are using LTC4162-LAD, you would use the LTC4162-LAD folder. If you are using LTC4162-L41, you would use the LTC4162-L41 folder, etc.
Note that LTC4162-L is not an orderable part number. Refer to…
Data gathered by LTC4162 is enough to monitor the battery
Firstly, thanks for picking this up.
So, If I am understanding this correctly, I have an LTC4162-SAD PCB, so therefore to modify the onboard firmware I should use the Mzero project (located in the SDK an LTC4162>c_code>examples>dc2038a>THC4162…
