BQ24074: Will not charge dead battery when system load is connected

Part Number: BQ24074

Hi all,

I am using the BQ24074 with a solar panel at the input (6V, 370mA), a 3.7V Li-Ion battery, and a system load.  When the battery goes dead, the 6V solar panel will not charge the battery unless I remove the system load.  If I remove the load, the battery will charge as expected.  Once the battery has a tiny charge, I can reconnect the load and away we go.  This is a problem, because it requires our customers to turn OFF the device (system load) when battery dies to start charging again.

Can anyone help me by explaining why this is happening?  What may be possible solutions? 

Thank you!
