ICS1708
SoftStart
Conditioning Charge
New, over-discharged, and batteries out of long term storage may exhibit an initial high impedance conditions in response to charging, as
shown in Figure 2. Unless dealt with, this high impedance condition can cause a voltage peak and -
V condition at the beginning of the
charge cycle that can appear to be the response of an already full battery. To manage this condition, the
ICS1708
applies a
SoftStart
conditioning charge.

The
SoftStart
charge eases batteries into the fast charge stage by gradually increasing the duty cycle of the charge. The gradual increase
alleviates the voltage peak and the -
V condition. The duty cycle of the applied current is increased to the fast charge rate, as shown in
Figure 3, by extending the current pulse on every cycle until the pulse is about 1.1 seconds in duration. The initial current pulse is
approximately 200ms. The CMN indicator is a continuous active low during the
SoftStart
conditioning stage.
