I am trouble shooting an older design using bq2004E. The problem is that fast charging never starts except when the powered is recycled, othewise the batteries are always discharged. The INH is disabled (pulled high) and Vsense is grounded. So according the data sheets, the only other way to start the fast charge cycle is for Vcell to fall below max cell voltage. But by design Vcell is always less than MCV. This condition is always met even when battery chargeing is terminated. In other words when charging is complete, Vbat is less than MCV. And yet the new charge cycle is expected to start when Vbat falls less than MVC !. What am I missing here ?
