NCP1800
Single-Cell Lithium Ion
Battery Charge Controller
The NCP1800 is a constant current, constant voltage (CCCV)
lithium ion battery charge controller. The external sense resistor sets
the full charging current, and the termination current is 10% of the full
charge current (0.1 C). The voltage is regulated at
1% during the
final charge stage. There is virtually zero drain on the battery when the
input power is removed.

Operation Descriptions
The NCP1800 is a linear lithium ion (Li-ion) battery
charge controller and provides the necessary control
functions for charging Li-ion batteries precisely and safely.
It features the constant current and constant voltage method
(CCCV) of charging.
Conditioning and Pre-charge Phase
The NCP1800 initiates a charging cycle upon toggling the
COMP/DIS to LOW or application of the valid external
power source (i.e. V
UVLO
t V
CC
t V
OVLO
) with the
Li-ion battery present or when the Li-ion battery is inserted.
Before a charge cycle can begin, the battery conditions are
verified to be within safe limits. The battery will not be
charged when its voltage is less than 0.9 V or higher than
V
SOVLO
.
Li-ion batteries can be easily damaged when fast charged
from a completely discharged state. Also, a fully discharged
Li-ion battery may indicate an abnormal battery condition.
With the built-in safety features of the NCP1800, the Li-ion
battery pre-charges (Pre-Charge Phase) at 10% of the full
rated charging current (I
REG
) when the battery voltage is
lower than V
PCTH
and the CFLG pin is HIGH. Typically, the
battery voltage reaches V
PCTH
in a few minutes and then the
Full Charge phase begins.
Full Charge (Current Regulation) Phase
When the battery voltage reaches V
PCTH
, the NCP1800
begins fast charging the battery with full rate charging
current I
REG
. The NCP1800 monitors the charging current
at the I
SNS
input pin by the voltage drop across a current
sense resistor, R
SNS
, and the charging current is maintained
at I
REG
by the pass transistor throughout the full charge
phase.
I
REG
is determined by R
SNS
and R
ISEL
with the following
formula:
IREG
+
(1.19
12 k)
(RISEL
RSNS)
And with R
ISEL
= 60 k and R
SNS
= 0.4
W, I
REG
= 0.6 A.
Since the external P channel MOSFET is used to regulate
the current to charge the battery and operates in linear mode
as a linear regulator, power is dissipated in the pass
transistor. Designing with a very well regulated external
adaptor (e.g. 5.1 V
1%) can help to minimize the heat
dissipation in the pass transistor. Care must be taken in heat
sink designing in enclosed environments such as inside the
battery operated portables or cellular phones.
The Full Charge phase continues until the battery voltage
reaches V
REG
. The NCP1800 comes in two options with
V
REG
thresholds of 4.1 and 4.2 V.
Final Charge (Voltage Regulation) Phase
Once the battery voltage reaches V
REG
, the pass transistor
is controlled to regulate the voltage across the battery and the
Final Charge phase (constant voltage mode) begins. Once
the charger is in the Final Charge phase, the charger
maintains a regulated voltage and the charging current will
begin to decrease and is dependent on the state of the charge
of the battery. As the battery approaches a fully charged
condition, the charge current falls to a very low value.
Trickle Charge Phase
During the Final Charge phase, the charging current
continues to decrease and the NCP1800 monitors the
charging current through the current sense resistor R
SNS
.
When the charging current decreases to such a level that I
SNS
< 0.1 X I
REG
, the CFLG pin is set to LOW and the Trickle
Charge phase begins. The charger stays in the Trickle
Charge phase until any fault modes are detected or the
COMP/DIS pin is pulled low to start over the charging cycle.

Selecting External Components
External Adaptor Power Supply Voltage Selection
Since the NCP1800 is using a linear, charging algorithm,
the efficiency is lower. Adapter voltage selection must be
done carefully in order to minimize the heat dissipation. In
general, the power supply input voltage should be around
5.0 to 6.0 V. The minimum input voltage should be chosen
to minimize the heat dissipation in the system. Excessively
high input voltages can cause too much heat dissipation and
will complicate the thermal design in applications like
cellular phones. With the overvoltage protection feature of
the NCP1800, input voltages higher than 7.0 V will activate
the overvoltage protection circuit and disconnect the power
supply input to the battery and other circuitry.

If the output voltage accuracy is 5%, then a typ. 5.2 V
5% output voltage adaptor must be used.
And for a very good regulated adaptor of accuracy 1%, 5.0
V
1% output voltage adaptor can then be used. It is obvious
that if tighter tolerance adaptors are used, heat dissipation
can be minimized by using lower nominal voltage adaptors.
Pass Element Selection
The type and size of the pass transistor is determined by
input-output differential voltage, charging current, current
sense resistor and the type of blocking diode used.
The selected pass element must satisfy the following
criteria:
Drop across pass element =
VIN(min)
*
Li- ion regulated voltage
*
VF
*
IREG
RSNS
With:
VIN(min)
+
5.0 V
VREG

IREG

0.6 A
Dropout across pass element =
5.0 V
*
4.2 V
*
0.38 V
*
(0.6 A) (0.4
W
)
+
0.18 V
Maximum R
DS(on)
should be less than (0.18 V)/(0.6 A) =
0.3
W at 0.6 A.
VIN(min)
+
5.0 V
VREG
+
4.2 V
RSNS
+
2.0
W
IREG
+
0.12 A
Dropout across pass element = 5.0 V - 4.2 V - 0.43 V -
(0.12)(2.0
W) = 0.13 V.
Therefore, maximum R
DS(on)
should be less than
(0.13 V)/(0.12 A) = 1.08
W at 0.12 A.
External Output Capacitor
Any good quality output filter can be used, independent of
the capacitor's minimum ESR. However, a 10
mF tantalum
capacitor or electrolytic capacitor is recommended at the
output to suppress fast ramping spikes at the V
SNS
input and
to ensure stability for 1.0 A at full range. The capacitor
should be mounted with the shortest possible lead or track
length to the VSNS and GND pins.
Current Sense Resistor
The charging current can be set by the value of the current
sense resistor as in the previous formula. Proper de-rating
is advised when selecting the power dissipation rating of the
resistor. If necessary, R
ISEL
can also be changed for proper
selection of the R
SNS
values. Take note of the recommended
full-char ge current ranges specified in the electrical
characteristics section. Also notice the effect of RISEL on
the accuracy of pre-charge current and end-of-charge
detection as noted in Figures 10 and 12, respectively.
