ADVANCED BATTERY CHARGER APPLICATION
The above circuit can be used to realize an advanced battery
charger that has the capability to monitor the exact net current
that flows in and out the battery as show in
output signal of the LMP8602/LMP8602Q/LMP8603/LM-
K2 = 5 for LMP8602
K2 = 10 for LMP8603

P8603Q is digitized with the A/D converter and used as an
input for the charge controller. The charge controller can be
used to regulate the charger circuit to deliver exactly the cur-
rent that is required by the load, avoiding overcharging a fully
loaded battery.
