FUNCTIONAL DESCRIPTION
INTRODUCTION
Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not
available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.
FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL PIN DESCRIPTION
CHARGER
CHRGRAW
1. Charger input. The charger voltage is measured through
an ADC at this pin. The UVBUS pin must be shorted to
CHRGRAW in cases where the charger is being supplied
from the USB cable. The minimum voltage for this pin
depends on BATTMIN threshold value (see Battery
2. Output to battery supplied accessories. The battery
voltage can be applied to an accessory by enabling the
charge path for the accessory via the CHRGRAW pin. To
accomplish this, the charger needs to be configured in
reverse supply mode.
CHRGCTRL1
Driver output for charger path FET M1.
CHRGCTRL2
Driver output for charger path FET M2.
CHRGISNS
Charge current sensing point 1. The charge current is read
by monitoring the voltage drop over the charge current
100 m
Ω sense resistor connected between CHRGISNS and
BPSNS.
BPSNS
1. BP sense point. BP voltage is sensed at this pin and
compared with the voltage at CHRGRAW.
2. Charge current sensing point 2. The charge current is
read by monitoring the voltage drop over the charge current
100 m
Ω sense resistor. This resistor is connected between
CHRGISNS and BPSNS.
BP
This pin is the application supply point, the input supply to
the IC core circuitry. The application supply voltage is sensed
through an ADC at this pin.
BATTFET
Driver output for battery path FET M3. If no charging
system is required, the pin BATTFET must be floating. When
single path is implemented, it must be connected to ground.
BATTISNS
Battery current sensing point 1. The current flowing out of
and into the battery can be read via the ADC by monitoring
the voltage drop over the sense resistor between BATT and
BATTISNS.
BATT
Battery positive terminal. Battery current sensing point 2.
The supply voltage of the battery is sensed through an ADC
on this pin. The current flowing out of and into the battery can
be read via the ADC by monitoring the voltage drop over the
sense resistor between BATT and BATTISNS.
BATTISNSCC
Accumulated current counter current sensing point. This is
the coulomb counter current sense point. It should be
connected directly to the 0.020
Ω sense resistor via a
separate route from BATTISNS. The coulomb counter
monitors the current flowing in/out of the battery by
integrating the voltage drop over the BATTISNCC and the
BATT pin.
CFP AND CFM
Accumulated current filter cap plus and minus terminals
respectively. The coulomb counter will require a 10 F output
capacitor connected between these pins to perform a first
order filtering of the signal across R1.
CHRGSE1B
An unregulated wall charger configuration can be built in
which case this pin must be pulled low. When charging
through USB, it can be left open since it is internally pulled up
to VCORE. The recommendation is to place an external FET
that can pull it low or left it open, depending on the charge
method.
CHRGLED
Trickle LED driver output 1. Since normal LED control via
the SPI bus is not always possible in the standalone
operation, a current sink is provided at the CHRGLED pin.
This LED is to be connected between this pin and
CHRGRAW.
GNDCHRG
Ground for charger interface.
