Li-ion/Li-Polymer Battery Charger
Accepting Two Power Sources
Features
The ISL9214A is a fully integrated low-cost single-cell Li-ion
or Li-polymer battery charger. The charger accepts two
power inputs, normally one from a USB (Universal Serial
Bus) port and the other from a desktop cradle. The
ISL9214A is an ideal charger for smart handheld devices
that need to communicate with a personal computer via
USB.
• Dual Input Power Sources for Cradle and USB
The ISL9214A features 28V maximum voltages for both the
cradle and the USB inputs. Due to the 28V rated inputs,
low-cost, large output tolerance adapters can be used safely.
When both inputs are powered, the cradle input is used to
charge the battery. The charge current is programmable for
the cradle input with a small resistor. The end-of-charge
current is also programmable by another external resistor.
The charger incorporates Thermaguard™ which protects the
IC against over-temperature. If the die temperature rises
above a typical value of +125°C, a thermal foldback function
reduces the charge current automatically to prevent further
temperature rise. The charger has two indication pins. The
PPR (power present) pin outputs an open-drain logic LOW
when either the cradle or the USB input power is attached.
The CHG (charge) pin is also an open-drain output that
indicates a logic LOW when the charge current is above a
minimum current level. When the charge current is below the
preset minimum current, the CHG pin will indicate a logic
HIGH signal. This status is latched and will be reset under
one of the following events:
• Charge Current Thermaguard™ for Thermal
Protection
• Complete Charger for Single-Cell Li-ion/Polymer Batteries
1. The part is disabled and re-enabled
2. The selected input source has been removed and reapplied
3. The USBON turns LOW
4. The BAT pin voltage falls below the recharge threshold
(~3.9V).

Functional Pin Description
IMIN (Pin 6)
CRDL (Pin 1)
IMIN is the programmable input for the end-of-charge
current. IMIN is calculated by using Equation 1:
Cradle input. This pin is usually connected to a cradle power
input. The maximum input voltage is 28V. The charge
current from this pin is programmable with the ICDL pin up to
1A. When this pin is connected to a power source, no charge
current is drawn from the USB pin. A 1µF or larger value
ceramic capacitor is recommended for decoupling.
Where RIMIN is in kΩ. IMIN is applicable for both cradle and
USB charging.
USB (Pin 2)
USBON (Pin 7)
USB input. This pin is usually connected to a USB port
power connector and other sources that are also acceptable.
The charge current from the USB pin is fixed at typically
380mA. A 1µF or larger value ceramic capacitor is
recommended for decoupling. It is also recommended to
have a 1Ω resistor in series with the decoupling capacitor to
prevent an over-shoot voltage when a USB cable is plugged
in.
The USBON pin is a control input to turn off the USB charge
function if desired. Connect to LOW or leave floating to turn
off USB charge.
PPR (Pin 3)
Power presence indication. An open-drain output pin, which
turns ON when either the USB input voltage or the CRDL
input voltage is above its POR level, regardless of the
charger is enabled or disabled, otherwise it turns OFF. This
pin provides a wake-up signal to a microprocessor when
either the cradle or the USB power is connected.
CHG (Pin 4)
Charge indication pin. An open-drain output, which turns ON
when the charge current is above programmable threshold,
otherwise it turns OFF.
550
I MIN = ---------------R IMIN
( mA )
(EQ. 1)
GND (Pin 8)
System ground.
ICDL (Pin 9)
The ICDL pin has two functions. The first function is to
program the cradle charge current during the
constant-current mode. The voltage of this pin is 1.22V
during the constant-current mode of the cradle charger. The
constant-current mode current is programmed by using
Equation 2:
6820
I CDL = ----------------R ICDL
( mA )
(EQ. 2)
where RICDL is the resistor in kΩ, connected to the ICDL pin
(see “Typical Applications” on page 3).
It is recommended that the charge current be programmed
in the range of 100mA to 1000mA.
EN (Pin 5)
Enable logic input. Connect to LOW or leave floating to
enable the charger.
7
The second function of the ICDL pin is to monitor the actual
charge current. The voltage of this pin, VICDL, is proportional
to the actual charge current, ICHG.
FN6698.0
May 5, 2008
ISL9214A
The cradle charge current should be programmed equal or
higher than the USB current; otherwise, the ICDL pin voltage
will be higher than 1.22V during the constant-current mode
when the USB charger is working. The charger still works
properly but the accuracy of the current monitoring voltage
degrades and saturates at approximately 2.1V.
BAT (Pin 10)
Charger output pin. Connect this pin to the battery pack or
the battery cell. A 1µF or larger value ceramic capacitor is
recommended for decoupling. The charger relies on the
battery for stability so a battery should always be connected
to the BAT pin.
Description
The ISL9214A is designed for a single-cell Li-ion or Li-polymer
battery charging circuit that accepts both a USB port and a
desktop cradle as its power source. While the charge-current
from the USB input source is fixed at 380mA, the charge
current from the cradle input is programmable between 0.1A
and 1.0A by the resistor RICDL. Similarly, the end-of-charge
current is programmable by connecting a resistor at the IMIN
pin. The end-of-charge threshold can be calculated with the
Equation 1 given in the “Functional Pin Description” on
page 7. The same threshold applies to both the cradle and the
USB inputs.
Input Auto Selection
When both input sources are present, the charger selects
only one power source to charge the battery. When the
CRDL input is higher than the POR threshold, CRDL is
selected as the power source, otherwise, the USB input is
selected. If the CRDL input voltage is below the battery
voltage but the USB input voltage is higher than the battery
voltage, then the USB input is used to charge the battery.
The control circuit always breaks both internal power
devices before switching from one power source to the other
to avoid a cross conduction of both power MOSFETs.
The USBON pin is equivalent to a logic LOW when left
floating. Typically, the P-Channel MOSFET for the USB input
has an rDS(ON) of 600mΩ at room temperature. With a
380mA charge current, the typical head room is 228mV.
Thus, if the input voltage drops to a level that the voltage
difference between the USB pin and the BAT pin is less than
228mV, the rDS(ON) becomes a limiting factor of the
charge-current; and the charger drops out the
constant-current regulation.
Cradle Charge Current
The cradle charge current is enabled by the EN pin only; the
USBON pin has no control on the cradle charge current. The
cradle charge current is programmed with the external
resistor connected between the ICDL pin and the GND pin.
The current can be calculated with Equation 2 given in the
ICDL pin description on page 7. The typical rDS(ON) of the
P-Channel MOSFET for the CRDL input is 600mΩ at room
temperature. When the head room between the input and
output voltages is small, the actual charge current, similar to
the USB case, could be limited by the rDS(ON). On the other
hand, if the headroom between the input and output voltages
is large, the charge current may be limited by the thermal
foldback threshold.
Floating Charge Voltage
The floating voltage during the constant voltage phase is
4.2V. The floating voltage has an 1% accuracy over the
ambient temperature range of -40°C to +85°C.
Trickle Charge Current
When the battery voltage is below the minimum battery
voltage VMIN given in the “Electrical Specification” table on
page 4, the charger operates in a trickle/preconditioning
mode, where the charge current is typically 18% of the
programmed charge current for the cradle input. If power
comes from the USB input, the trickle current is
approximately 80mA.
End-Of-Charge Indication
USB Charge Current
When the USB port is selected as the power source, the
charge-current is enabled by the logic input at the USBON
pin. When the USBON is driven to logic LOW, the charger is
disabled. When the USBON is driven to logic HIGH, the
charge current is fixed at a typical value of 380mA. Thus, for
the USB input, the USBON pin has a similar function as the
EN pin. Table 3 describes the USB charge control by both
the USBON pin and EN pin:
1. The part is disabled and re-enabled
2. The selected input source has been removed and
reapplied

When an EOC condition (charge current falls below IMIN
during constant voltage charge) is encountered, the CHG pin
internal open-drain MOSFET turns off. The IMIN threshold is
programmable by the resistor at the IMIN pin for both cradle
and USB inputs. Once the EOC condition is reached, the
status is latched and can be reset at one of the following
conditions:
3. The USBON turns LOW and turns back to HIGH for the
USB input

Power Presence Indication
When either the USB or the cradle input voltage is above the
POR threshold, the PPR pin internal open-drain MOSFET
turns on indicating the presence of input power.
Power-Good Conditions
Even if there is power present, the charger will not deliver
any current to the output if the power-good conditions are
not met. The following two conditions together define the
power-good voltage range:
1. VCDRL or VUSB > VPOR
2. VCDRL or VUSB - VBAT > VOS
where VPOR is the power-on reset threshold and VOS is the
offset voltage for the input and output voltage comparator. All
of these thresholds have hysteresis, as given in the
“Electrical Specification” table on page 4. The charger will

Thermal Foldback (Thermaguard™)
Due to the inductance of the power leads of the wall adapter
or USB source, the input capacitor type must be properly
selected to prevent high voltage transient during a hot-plug
event. A tantalum capacitor is a good choice for its high
ESR, which provides damping to the voltage transient. Multilayer ceramic capacitors, however, have a very low ESR,
and hence, when chosen as input capacitors, a 1Ω series
resistor must be used (as shown in the “Typical Applications”
on page 3) in order to provide adequate damping.
State Diagram
The state diagram for the charger functions is shown in
Figure 12. The diagram starts with the Power-Off state.

threshold, the charge resets it self. If both input voltages are
above the POR threshold, the charger selects the CRDL
input as the power source. Then, if the EN pin is at a logic
HIGH voltage, the charger stays in disabled state. If the EN
pin goes LOW, the fast charge starts. Any time the EN pin
turns HIGH, the charger returns to the disabled state. When
the EOC condition is reached, the CHG will turn to logic
HIGH to indicate a charge complete status but the charge
will continue. The EOC condition is then latched until one of
the four re-charge conditions is encountered, as shown in
Figure 11.
