DESCRIPTION
The AIC1783 fast charge controller IC is designed
for intelligent charging of NiMH or NiCd batteries
without the risk of overcharge.
(-0.25%) and
V
0
detection (peak voltage timer)
V
detection
are the primary methods employed by the
AIC1783 to terminate fast charge. The fast charge
can also be cut off by maximum battery voltage
along with the safety timer to prevent charging
under fault conditions of the charging system or
the battery itself.
The safety timer period is adjustable for flexible
usage that AIC1783 could be applied in the wide
range of battery capacity. Test mode is provided
for charger manufactures to dramatically reduce
production test time.
