We are designing a charger for our application where we have used LTC4001 IC. We are getting 1.213V at PROG and IDET pin but the output voltage is coming 3.012V only.
Any suggestion or idea what to do?
Is this operation with or without a battery attached? This particular part was designed to operate with the battery attached.
If the battery is attahced is there a fault indicated on the Fault pin or temperature fault indicated on the /CHRG pin?
I also notice that the schematic only shows a 0.1uF on VIN. Is there a 10uF on the VIN pin not shown? (This is not related to the problem.)
