The MCP73113/4 are highly integrated Li-Ion battery
charge management controllers for use in spacelimited
and
cost-sensitive
applications.
The
MCP73113/4 devices provide specific charge
algorithms for Li-Ion/Li-Polymer batteries to achieve
optimal capacity and safety in the shortest charging
time possible. Along with their small physical size, the
low number of external components make the
MCP73113/4 ideally suitable for portable applications.
The absolute maximum voltage, up to 18V, allows the
use of MCP73113/4 in harsh environments, such as
low cost wall wart or voltage spikes from plug/unplug.
The MCP73113/4 devices employ a constant
current/constant voltage charge algorithm. The various
charging voltage regulations provide design engineers
flexibility to use in different applications. The fast
charge, constant current value is set with one external
resistor from 130 mA to 1100 mA. The MCP73113/4
devices limit the charge current based on die
temperature during high power or high ambient
conditions. This thermal regulation optimizes the
charge cycle time while maintaining device reliability.
The PROG pin of the MCP73113/4 also serves as
enable pin. When high impedance is applied, the
MCP73113/4 will be in standby mode.
The MCP73113/4 devices are fully specified over the
ambient temperature range of -40°C to +85°C. They
are available in a 10 lead, DFN package.

DETAILED DESCRIPTION
5.3.2
5.1
Undervoltage Lockout (UVLO)
The battery charge control output is the drain terminal
of an internal P-channel MOSFET. The MCP73113/4
devices provide constant current and voltage
regulation to the battery pack by controlling this
MOSFET in the linear region. The battery charge
control output should be connected to the positive
terminal of the battery pack.
An internal undervoltage lockout (UVLO) circuit
monitors the input voltage and keeps the charger in
shutdown mode until the input supply rises above the
UVLO threshold. In the event a battery is present when
the input power is applied, the input supply must rise
approximately 150 mV above the battery voltage
before the MCP73113/4 device become operational.
The UVLO circuit places the device in shutdown mode
if the input supply falls to approximately 150 mV above
the battery voltage.The UVLO circuit is always active.
At any time, the input supply is below the UVLO
threshold or approximately 150 mV of the voltage at the
VBAT pin, the MCP73113/4 device is placed in a
shutdown mode.
5.2
Overvoltage Protection (OVP)
An internal overvoltage protection (OVP) circuit
monitors the input voltage and keeps the charger in
shutdown mode when the input supply rises above the
OVP threshold. The hysteresis of OVP is approximately 150 mV for the MCP73113/4 device.
The MCP73113/4 device is operational between UVLO
and OVP threshold. The OVP circuit is also recognized
as overvoltage lock out (OVLO).
5.3
Charge Qualification
When the input power is applied, the input supply must
rise 150 mV above the battery voltage before the
MCP73113/4 becomes operational.
The automatic power down circuit places the device in
a shutdown mode if the input supply falls to within
+50 mV of the battery voltage.
The automatic circuit is always active. At any time the
input supply is within +50 mV of the voltage at the
VBAT pin, the MCP73113/4 is placed in a shutdown
mode.
For a charge cycle to begin, the automatic power
down conditions must be met and the charge enable
input must be above the input high threshold.
5.3.1
BATTERY MANAGEMENT INPUT
SUPPLY (VDD)
The VDD input is the input supply to the MCP73113/4.
The MCP73113/4 automatically enters a Power-down
mode if the voltage on the VDD input falls to within
+50 mV of the battery voltage. This feature prevents
draining the battery pack when the VDD supply is not
present.
© 2009 Microchip Technology Inc.
5.3.3
BATTERY CHARGE CONTROL
OUTPUT (VBAT)
BATTERY DETECTION
The MCP73113/4 detects the battery presence with
charging of the output capacitor. The charge flow will
initiate when the voltage on VBAT is pulled below the
VRECHARGE threshold. Refer to Section 1.0 “Electrical
Characteristics” for VRECHARGE values. The value will
be the same for non-rechargeable device.
When VBAT > VREG + Hysteresis, the charge will be
suspended or not start, depends on the condition to
prevent over charge that may occur.
5.4
Preconditioning
If the voltage at the VBAT pin is less than the
preconditioning threshold, the MCP73113/4 device
enters a preconditioning mode. The preconditioning
threshold is factory set. Refer to Section 1.0
“Electrical Characteristics” for preconditioning
threshold options.
In this mode, the MCP73113/4 device supplies 10% of
the fast charge current (established with the value of
the resistor connected to the PROG pin) to the battery.
When the voltage at the VBAT pin rises above the preconditioning threshold, the MCP73113/4 device enters
the constant current (fast charge) mode.
Note:
5.4.1
The MCP73113/4 also offer options with
no preconditioning.
TIMER EXPIRED DURING
PRECONDITIONING MODE
If the internal timer expires before the voltage threshold
is reached for fast charge mode, a timer fault is
indicated and the charge cycle terminates. The
MCP73113/4 device remains in this condition until the
battery is removed or input power is cycled. If the
battery is removed, the MCP73113/4 device enters the
standby mode where it remains until a battery is
reinserted.
Note:
The typical preconditioning timer for
MCP73113/4 is 32 minutes. The
MCP73113/4 also offer options with no
preconditioning timer.

Constant Current MODE - Fast
Charge
During the constant current mode, the programmed
charge current is supplied to the battery or load.
The charge current is established using a single
resistor from PROG to VSS. The program resistor and
the charge current are calculated using the following
equation:

remainsin this condition until the battery is removed. If
the battery is removed or input power is cycled. The
MCP73113/4 device enters the Stand-by mode where
it remains until a battery is reinserted.
5.6
Constant Voltage Mode
When the voltage at the VBAT pin reaches the
regulation voltage, VREG, constant voltage regulation
begins. The regulation voltage is factory set to 4.10V,
4.20V, 4.35V or 4.40V with a tolerance of ± 0.5%.
EQUATION 5-2:
R PROG = 10
Constant current mode is maintained until the voltage
at the VBAT pin reaches the regulation voltage, VREG.
When constant current mode is invoked, the internal
timer is reset.

Charge Termination
The charge cycle is terminated when, during constant
voltage mode, the average charge current diminishes
below a threshold established with the value of 5%,
7.5%, 10% or 20% of fast charge current or internal
timer has expired. A 1 ms filter time on the termination
comparator ensures that transient load conditions do
not result in premature charge cycle termination. The
timer period is factory set and can be disabled. Refer to
Section 1.0 “Electrical Characteristics” for timer
period options.
5.8
Automatic Recharge
The MCP73113/4 device continuously monitors the
voltage at the VBAT pin in the charge complete mode. If
the voltage drops below the recharge threshold,
another charge cycle begins and current is once again
supplied to the battery or load. The recharge threshold
is factory set. Refer to Section 1.0 “Electrical
Characteristics” for recharge threshold options.
Note:
The MCP73113/4 also offer options with
no automatic recharge.
For the MCP73113/4 devices with no recharge option,
the MCP73113/4 will go into standby mode when
termination condition is met. The charge will not restart
until following condition has met:
• Battery is removed from system and insert again.
• VDD is removed and plug in again
• RPROG is disconnected (or high impedance) and
reconnect

THERMAL REGULATION
The MCP73113/4 shall limit the charge current based
on the die temperature. The thermal regulation
optimizes the charge cycle time while maintaining
device reliability. Figure 5-1 depicts the thermal
regulation for the MCP73113/4 device. Refer to
Section 1.0 “Electrical Characteristics” for thermal
package resistances and Section 6.1.1.2 “Thermal
Considerations” for calculating power dissipation.

THERMAL SHUTDOWN
The MCP73113/4 suspends charge if the die
temperature exceeds +150°C. Charging will resume
when the die temperature has cooled by
approximately 10°C. The thermal shutdown is a
secondary safety feature in the event that there is a
failure within the thermal regulation circuitry.

BATTERY SHORT PROTECTION
Once a single-cell Li-Ion battery is detected, an internal
battery short protection (BSP) circuit starts monitoring
the battery voltage. When VBAT falls below a typical
1.7V battery short protection threshold voltage, the
charging behavior is postponed. 25 mA (typical) detection current is supplied for recovering from battery short
condition.
Preconditioning mode resumes when VBAT raises
above battery short protection threshold. The battery
voltage must rise approximately 150 mV above the
battery short protection voltage before the
MCP73113/4 device become operational.
Status Indicator
The charge status outputs are open-drain outputs with
two different states: Low (L), and High Impedance
(Hi-Z). The charge status outputs can be used to
illuminate LEDs. Optionally, the charge status outputs
can be used as an interface to a host microcontroller.
Table 5-2 summarize the state of the status outputs
during a charge cycle.

Application Circuit Design
Due to the low efficiency of linear charging, the most
important factors are thermal design and cost, which
are a direct function of the input voltage, output current
and thermal impedance between the battery charger
and the ambient cooling air. The worst-case situation is
when the device has transitioned from the
Preconditioning mode to the Constant-current mode. In
this situation, the battery charger has to dissipate the
maximum power. A trade-off must be made between
the charge current, cost and thermal requirements of
the charger.
© 2009 Microchip Technology Inc.
COMPONENT SELECTION
Selection of the external components in Figure 6-1 is
crucial to the integrity and reliability of the charging
system. The following discussion is intended as a guide
for the component selection process.
6.1.1.1
Charge Current
The preferred fast charge current for Li-Ion / Li-Poly
cells is below the 1C rate, with an absolute maximum
current at the 2C rate. The recommended fast charge
current should be obtained from battery
manufacturer. For example, a 500 mAh battery pack
with 0.7C preferred fast charge current has a charge
current of 350 mA. Charging at this rate provides the
shortest charge cycle times without degradation to the
battery pack performance or life.
Note:
Please consult with your battery supplier
or refer to battery data sheet for preferred
charge rate.
DS22183B-page 21
MCP73113/4
6.1.1.2
Thermal Considerations
The worst-case power dissipation in the battery
charger occurs when the input voltage is at the
maximum and the device has transitioned from the
Preconditioning mode to the Constant-current mode. In
this case, the power dissipation is:
PowerDissipation = ( V
DDMAX

PTHMIN
)×I
REGMAX
Where:
VDDMAX
=
the maximum input voltage
IREGMAX
=
the maximum fast charge current
VPTHMIN
=
the minimum transition threshold
voltage
A minimum of 16V rated 1 µF, is recommended to apply
for output capacitor and a minimum of 25V rated 1 µF,
is recommended to apply for input capacitor for typical
applications.

Tolerance
Power dissipation with a 5V, ±10% input voltage
source, 500 mA ±10% and preconditioning threshold
voltage at 2.7V is:
Virtually any good quality output filter capacitor can be
used, independent of the capacitor’s minimum
Effective Series Resistance (ESR) value. The actual
value of the capacitor (and its associated ESR)
depends on the output load current. A 1 µF ceramic,
tantalum or aluminum electrolytic capacitor at the
output is usually sufficient to ensure stability.
EQUATION 6-1:
6.1.1.4
PowerDissipation = ( 5.5V – 2.7V ) × 550mA = 1.54W
This power dissipation with the battery charger in the
DFN-10 package will result approximately 63°C above
room temperature.
6.1.1.3
Reverse-Blocking Protection
The MCP73113/4 provide protection from a faulted or
shorted input. Without the protection, a faulted or
shorted input would discharge the battery pack through
the body diode of the internal pass transistor.
External Capacitors
The MCP73113/4 are stable with or without a battery
load. In order to maintain good AC stability in the
Constant-voltage mode, a minimum capacitance of
1 µF is recommended to bypass the VBAT pin to VSS.
This capacitance provides compensation when there is
no battery load. In addition, the battery and
interconnections appear inductive at high frequencies.
These elements are in the control feedback loop during
Constant-voltage mode. Therefore, the bypass
capacitance may be necessary to compensate for the
inductive nature of the battery pack.

PCB Layout Issues
For optimum voltage regulation, place the battery pack
as close as possible to the device’s VBAT and VSS pins,
recommended to minimize voltage drops along the
high current-carrying PCB traces.
If the PCB layout is used as a heatsink, adding many
vias in the heatsink pad can help conduct more heat to
the backplane of the PCB, thus reducing the maximum
junction temperature. Figure 6-4 and Figure 6-5 depict
a typical layout with PCB heatsinking.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
