The nCHG behaves as expected when the battery, being charged, is disconnected from the load. However, when the battery is connected to a very small load (> 100uA), the nCHG stays low way beyond the 1.5mA termination current (I have the charging current set to 15mA). It looks like nCHG goes Hi-z when the termination current is about the same as the load current (>100uA). Why is this? I do have the recommended RC on the ISET pin.
