The main battery charger (MBC) module provides a
complete constant-current/constant-voltage linear charger
controller for lithium-ion (Li-ion) batteries (in CCCV
configuration) or a programmable battery threshold level
detector for end-of-charge indication (configuration
BATMAX). Nickel-cadmium (NiCd) and Nickel metal
hydride (NiMH) batteries can also be charged with
constant current.
Only an external power PNP transistor is required to
control the charge current. The CC and CCCV control
circuitry is fully integrated in the PCF50603 charging
module.
In CCCV configuration the charging process for
Li-ion/Li-pol batteries is performed under control of the
host controller. The communication between the
PCF50603 charger module and the host controller is
interrupt based, which simplifies the control of the
PCF50603.

The fast charge current is determined by the value of the
external sense resistor. The charge current in the pre and
trickle charge phase is programmable as a ratio of the fast
charge current.
In BATMAX configuration an end-of-charge indication is
available on the BATMAX pin.

The PCF50603 charger circuitry supports the following
type of charger plugs (see Fig.10):
Regulated charger plugs with output voltage at least
0.5 V above the battery voltage with a maximum of 10 V
and with current limitation up to 3C of the used battery
(CCCV and BATMAX configuration)
Non regulated charger plugs with peak output voltages
up to 20 V with a duration of less than 14 ms and with
current limitation up to 3C of the used battery (BATMAX
configuration only).
Non regulated charger plug.
