Are LTC4162EUFD-LAD and LTC4162EUFD-LADM identical?

Hi,

I made a battery charge board using  LTC4162EUFD-LAD. At moment the code LTC4162EUFD-LAD is difficult to find on the electronic market so I would like to use the chip code LTC4162EUFD-LADM . Are they identical?

I read the datasheet and I found the follow descriptions:

  • LTC4162EUFD-LAD              I2C Adjustable Voltage
  • LTC4162EUFD-LADM           I2C Adjustable Voltage MPPT ON

What it means? Any differences? In my application I reset via firmware the MPPT bit in order to disable the MPPT algortihm.

Can I still disable via firmware the MPPT algorithm in LTC4162EUFD-LADM ? 

I need to charge lithium battery ( 2 cells) with a charger 12 Volt/2 A .

Thank you.

Regards,

Gaetano
