Output pin for charging control. An external photocoupler is drived
from the output for constant voltage and constant current charging
control.
Constant current loop reference Input.
Charging current sensing input . It is connected to a sense resistor
(system ground)
Ground
Charging current monitoring feedback input. monitoring output
voltage can be changed by alternating the value of external resistor
which is connected to the pin6, CHA-
LDO output through a resistor divider.
LDO driving output. This is connected to the base of external TR
(KSA539)
voltage for micro controller reaches the threshold voltage. Error
signal becomes ON when the voltage reaches 4.8V.
(With hysteresis 60mV)
Charging current monitoring output. This pin is connected to a micro
controller and detects the amplified voltage derived from CS pin.
Reference current control input. The Amplifier reference current is
controlled according to the resistor which is connected to the pin
I
normally connected to the Battery charger output through a resistor
divider.
Power supply input. The typical operating voltage range is 2.5V to
16V.
LDO dropout error flag. This keeps the error signal off until the bias
LDO output voltage sensing input. It is normally connected to the
REF
Voltage sensing input for constant Battery voltage control. It is
.
