The LX2206 enters a low quiescent
current sleep mode when power is
removed or when it is logically
shutdown to minimize battery drain.
There are several protection features
which include: under voltage lock out,
inrush current limiting, reverse current
blocking on the IN pin, a thermal loop
to reduce charge current to maintain a
low die temperature, an unsafe battery
temperature charge inhibitor, and
conditioning mode is provided for
deeply discharged batteries.

The LX2206 can be used with a
wall adapter or USB power source to
charge a single cell Lithium Ion or
Lithium Polymer battery. There are
two logic selectable and programmable charge current levels which can
be set from anywhere between 50mA
to 1A. The termination current is 1/10
the charge level set by the High Level
Programming Current Pin.
Power status indicators (STAT and
DCOK) can be configured to show
charge in progress, battery fully
charged and external power on. The
STAT pin is capable of sourcing or
sinking 10mA. The DCOK output is
an open drain output.

THEORY OF OPERATION
CONDITIONING CURRENT 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 HCP programmable constant current level.
Once the battery terminal voltage exceeds the conditioning
current threshold, the full constant current level is applied
(unless charging current is limited by one of the other
charger control loops).
CHARGE TERMINATION MODE
To increase system battery life and avoid float charging,
the LX2206 turns off the pass element once the battery has
been fully charged. The charge termination state occurs at
the end of constant voltage mode. The termination current
is set by the value of the resistor connected to the HCP
programming pin. The STAT pin changes state when
charging is completed.
TOP OFF CHARGE MODE
Once the charger has completed a charge cycle, if power
remains applied, the LX2206 enters a Voltage Monitoring
mode. In this mode the LX2206 monitors the battery
terminal voltage and applies a top off charge if the battery
voltage drops below the top of threshold.
The LX2206 supports battery charging from a system that
provides adapter power or USB power using the same
external connector. Figure 1 shows one example of a
system using a special USB adapter cable to determine
whether the power source is USB or Wall Adapter.
Similarly, if the system processor senses the absence of
USB data, it can logically set the H/L logic level high to
allow a higher charge current to be used.
USB CHARGE MODE AND CURRENT LIMIT
The LX2206 is fully compliant with, and supports, the
USB specifications – the Low Power Peripheral (100mA)
and High Power Peripherals (500mA). USB current levels
can be set using the appropriate values for the HCP and
LCP programming resistors. H/L logic input selects USB
high/low charge currents. When the SD pin is pulled high,
the USB input enters Suspend mode and will not present a
load to the IN pin.
DCOK
The IN input is monitored and DCOK is set to a logic
low to report the presence of the power source with
sufficient voltage to charge the battery. The DCOK
threshold is the larger of the UVLO threshold or the battery
voltage.
PROTECTION FEATURES
Conditioning Current Mode – If the battery terminal
voltage is less than 2.7V, the battery charger will reduce the
charge current to 5%. This also protects the appliance from
overheating by trying to drive the full charging current into a
short circuited battery.
Under Voltage Lockout – The charge cycle will not start
until the IN voltage rises above 3.8V. Hysteresis helps
alleviate chattering on and off.
Thermal Control loop – If the power dissipation of the
charger becomes excessive, the charge current will be
reduced to prevent the die temperature from getting above
140°C. This does not cause the charge cycle to stop.
Reverse current blocking – If IN input is grounded,
current will not flow from the BAT pin through the charger.
No external blocking diode is required on the input.
Sleep Mode – If the SD pin is a logic high, the charger
enters a sleep mode where a very low quiescent current
prevents drain from the battery.

GENERAL DESCRIPTION
The LX2206 is designed to charge a single cell Lithium
Ion battery using two steps: a constant current mode
followed by a constant voltage mode. The maximum
charging current during the Constant Current Mode of the
charging profile can be logically set (using H/L) to two
preprogrammed levels set by resistors connected to HCP
and LCP (High and Low current).
The charger will
terminate constant voltage charging once the current drops
below the taper current setting which is 10% of the high
charge current setting (determined by HCP resistor value).

APPLICATION NOTE
IHCP
The termination current determines the point at which
the charge cycle is terminated and the battery is determined
to be fully charged. The termination current is determined
by the value of the HCP programming current as
determined by the HCP programming resistor. For a value
of IHCP = 11.4µA (as was used in the previous example),
the termination current from the chart below can be seen to
be 9mA.
Term ination Current vs IHCP

Termination Current (in mA)
CURRENT PROGRAMMING RESISTORS
The LX2206 has two programming resistors to control
the battery charging current during the constant current
charging mode of the battery charging cycle. When the
H/L pin is high (selecting the High Current charging mode),
the charge current is determined by the value of the HCP
programming resistor. The maximum charge current is
determined by the programming current at either the HCP
or LCP programming pins (depending on the state of H/L);
the range of each of these channels is identical. The
programming current is the HCP or LCP pin voltage
(typically 1.25V) divided by the value of the programming
resistor. For example, the HCP current with a 110K resistor
to GND is:
Using the table below it can be seen that for a
programming current value of 11.4µA, the corresponding
maximum charge current is 92mA.
WWW . Microsemi .C OM
LAYOUT
In the layout of the Printed Circuit Board (PCB) it is
important to provide a solid path from the IC power and
ground pins to the power and ground planes of the PCB to
provide a good conduction path for heat. This insures the
LX2206 stays cool and can provide the maximum charge
current to minimize the time required to charge the battery.
For stability purposes and to reduce voltage switching
transients it is important to place capacitors close to the IN
and BAT pins. A 10µF capacitor (X5R or X7R dielectric)
is recommended.

BATTERY TEMPERATURE MONITOR
The LX2206 has an input to monitor the battery
temperature during battery charging; this method
assumes the battery pack contains a thermistor
expressly for this purpose. A typical Lithium ion battery
should only be charged from a range of 0°C to 60°C.
For this calculation, a Vishay NTHS0402N01N1003J
Thermistor was used. This thermistor is 327KΩ at 0°C,
100KΩ at 25°C and 24.9KΩ at 60°C. The thermistor
must be biased with a Thevenin voltage source and
series resistance to achieve the proper thresholds. A
fixed value resistor is added in series with the
thermistor to prevent it from becoming too low an
impedance at high temperatures and causing the TMP
input to default to off.
To finish the design it is necessary to create the
Thevenin Voltage and resistance using a voltage
divider from the input pin (IN).

R2 =
Using a value of RMIN that is equal to the thermistor
temperature at 60°C works well; therefore, for this
example, set the value of RMIN to 24.9K. This has the
effect of adding 24.9K to the thermistor resistance
values so it becomes 352KΩ at 0°C, 125KΩ at 25°C
and 49.8KΩ at 60°C.
R1 × RTH
= 14,800K
R1 − RTH
In this case, it is not necessary to use R2, because the
value is so large it is insignificant. In this case, R1 = RTH.
The equations for RTH and VTH are:

APPLICATION NOTE
INPUT POWER SOURCE DETECTION
In order to detect when the input power source has been
removed, the LX2206 requires that a small current (up to
200uA) momentarily flow out of the IN pin (in the reverse
direction). Once detected, the reverse IN current is shut off
(the IN pin becomes a very high impedance until an input
power source is later reapplied). In most applications, there
is sufficient loading on the IN pin from external circuitry to
accomplish this, which includes the “Full” and/or “Power
On” LED loads and the TFB resistor string. If there is no
external load on the IN pin, then it is recommended to
provide a 15k resistor from IN to GND as shown below.
