LTC4162-L Powerpath

Hi People,

It is not clear to me how the power path of the LTC4162 works. If the batteries are low and I put 35V on the input, which voltage does come on the Vout? According to the datasheet(power path controller) it is possible to directly power the load with the external voltage.....but is it than regulated at the set battery max voltage?

Thank you in advance,

Erik

    Hi Erik,

    You can generally consider it an ideal diode-OR. It will select the higher of the two voltages. In most applications, that means it will select VIN when VIN is present and the battery when VIN is not present.

    If you always want the battery voltage to power your load (rather than VIN), you can power your load from the battery node directly instead.
