PRELIMINARY DATA SHEET
THEORY OF OPERATION
GENERAL DESCRIPTION
Once the charger has completed a charge cycle, if
power remains applied, the LX2201 enters a VOLTAGE
MONITORING mode. In this mode the LX2201 monitors
the battery terminal voltage and applies a top off charge if
the battery voltage drops by more than 3% of full scale.
This feature is especially important for charging systems
in emergency equipment were usage is infrequent.
The LX2201 is designed to charge a single cell Lithium
Ion battery using two steps, a constant current step
followed by a constant voltage step. The basic charger
function uses the VDD pins as an input and BAT pins as
the output. This basic charger has a programmable
maximum current (programmable by the resistor value
between pin CCP to GND) which is the maximum charging
current during the CONSTANT CURRENT MODE of the
charging profile. The low dropout of the pass element
allows the battery to be charged from a loosely regulated
power supply. In the CONSTANT VOLTAGE MODE of
the charging profile the battery terminal voltage can be
regulated to 4.1V or 4.2V by strapping the VM pin to VDD
or GND, respectively. The charger will terminate constant
voltage charging once the current drops below the
minimum current setting (programmable by the resistor
value between pin CTP to GND).
The USB states insure compliance with the USB
specification. There are two current limitations imposed
by the specification; a Low Power peripheral is to draw
less than 100mA unless configure by the host controller as
a High Power peripheral which increases the current
limitation to 500mA. While the LX2201 will not
negotiate the host for the power designation it must insure
that the total current through VIN is less than, or equal to,
the stated current limitation. To accomplish this the
constant current loop will sense the current through VIN
and dynamically scale IBAT to maintain the desired input
current. It must be noted that the circuit does not limit the
input current and only scales the charging current. It is
possible that a system would draw more than 100mA
through VDD, and as a result fail USB compliance. In this
case the LX2201 would have scaled the charging current
to zero. This feature allows for the fastest possible charge
time in a USB configuration by allocating unused power
for the charger without limiting system performance or
features.
In the CONDITIONING CHARGE mode a conditioning
current is applied to batteries that are deeply discharged
and have a terminal voltage less than 60% of the constant
voltage level. The conditioning current is 5% of the CCP
programmable constant current level (except where it
might be limited in the USB states). Once the battery
terminal voltage exceeds the 60% level, the full constant
current level is applied (unless charging current is limited
by one of the other charger control loops).
The LX2201 has two unique features which assist in the
The LX2201 has a built in thermostat that will throttle
back the charging current to prevent the internal die
temperature from exceeding 150ºC. This feature prevents
the IC from getting hot enough to damage the board. This
feature can reduce the settings dictated by the constant
voltage and constant current control loops to reduce power
dissipation in the IC.
power control design.
The pass element can be
programmed by the VID0 pin to be bi-directional. This
allows the pass element to be used as a power switch to
provide a low impedance path around the Oring diode
without the need to use an external MOSFET. The other
feature is a logic output that enhances an external PMOS
FET when the LX2201 is in a charging mode (ie VDD >
VBAT). This provides a low impedance path around the
Oring diode that is typically used in a multiple source
power distribution. Lowering the voltage drop across the
Oring diode is especially helpful for use with low voltage
power inputs such as USB.
The LX2201 will turn off the pass element once the
battery has been fully charged. This is to prevent float
charging, which has been shown to reduce Lithium ion
battery life. The charge termination state occurs at the end
of the constant voltage charge mode where the battery
draws less current as it nears full capacity. The high
precision of the LX2201 in low current state lets the battery
continue charging to the point where the charging current
has dropped to the Charge Termination Current set by the
Charge Termination Programming Pin.

PRELIMINARY DATA SHEET
APPLICATION NOTE
CURRENT LIMITED POWER SUPPLIES
USB COMPLIANCE
When using input power supplies that are current limited
or have a high source impedance, the battery charging
current and/or load current can pull the VDD pin down very
close to the battery terminal voltage. This may cause the
LX2201 to enter an indeterminate state where it switches
between charge and discharge modes. To prevent this, the
PNP differential amplifier circuit of Figure 7 can be added;
this circuit adds an additional control loop that regulates the
charger headroom to 300mV by scaling back the battery
charging current.
To be compliant with the USB specification, the +5V
current must be less than 100mA in the low power mode
and less than 500mA in the high power mode. If the
LX2201 is configured as shown in Figure 3, it is possible
for the system to consume more than the maximum
allowed USB current (in which case the battery charging
current will have been fully scaled back). If it is not
possible to regulate the load current when charging from a
USB power source and strict adherence to the USB power
budget is required, the LX2201 configuration as shown in
Figure 6 can be used. In this case the system load can be
applied directly to the battery and the LX2201 will prevent
the load + battery from drawing more power than is
allowed for USB compliance. A better approach that
provides battery isolation is shown in Figure 8; in this
approach, the op amp circuit provides a current limiter that
prevents the system from exceeding the USB power limits.
The battery is only discharged if the AC adapter or USB
inputs are removed or current limited.
The internal power switch within the LX2201 requires
the power supply have a minimal level of strength to switch
from discharge mode to charge mode. If the power source is
severely current limited, the LX2201 may not open the
discharge switch. In this case, a small amount of current
will be allowed to flow into the battery unregulated. If left
in this state indefinitely, the current will eventually raise the
battery terminal voltage to the point where the batteries
internal protection circuitry will open the circuit. Typically,
the LX2201 requires a minimum of 80mA in USB mode
and 200mA using the VDD input to force the switchover to
charge mode. Alternatively, if weak power sources are
used, the switchover from discharge to charge mode can be
forced by momentarily setting VID0 and VID1 to a low
state, which will open the discharge switch allowing the
VDD voltage to rise so the LX2201 can enter charge mode.
LAYOUT GUIDELINES
•
•
It is important when laying out the LX2201 to
place 10uF ceramic capacitors close to the VDD
and VBAT IC terminals to filter switching
transients.
It is important to provide a low thermal impedance
path from the thermal pad on the bottom of the
LX2201 package to the ground plane of the circuit
board to maximize the heat dissipation.
