The MCP73213 is a highly integrated Li-Ion battery
charge management controller for use in space-limited
and cost-sensitive applications. The MCP73213
provides specific charge algorithms for dual-cell Li-Ion/
Li-Polymer batteries to achieve optimal capacity and
safety in the shortest charging time possible. Along
with its small physical size, the low number of external
components makes the MCP73213 ideally suitable for
portable applications. The absolute maximum voltage,
up to 18V, allows the use of MCP73213 in harsh
environments, such as low-cost wall wart or voltage
spikes from plug/unplug.
The MCP73213 employs 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 MCP73213 limits the charge current
based on die temperature during high-power or highambient conditions. This thermal regulation optimizes
the charge cycle time while maintaining device
reliability.
The PROG pin of the MCP73213 also serves as enable
pin. When high impedance is applied, the MCP73213
will be in Standby mode.
The MCP73213 is fully specified over the ambient
temperature range of -40°C to +85°C. The MCP73213
is 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 MCP73213
provides 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 MCP73213 device becomes 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.
Any time the input supply is below the UVLO threshold
or approximately 150 mV of the voltage at the VBAT pin,
the MCP73213 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
typical 13V OVP threshold. The OVP hysteresis is
approximately 150 mV for the MCP73213 device.
The MCP73213 device is operational between UVLO
and OVP thresholds. The OVP circuit is also recognized as overvoltage lockout (OVLO).
5.3
Charge Qualification
When the input power is applied, the input supply must
rise 150 mV above the battery voltage before the
MCP73213 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 MCP73213 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 MCP73213. The
MCP73213 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.
 2009-2014 Microchip Technology Inc.
5.3.3
BATTERY CHARGE CONTROL
OUTPUT (VBAT)
BATTERY DETECTION
The MCP73213 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 nonrechargeable devices.
When VBAT > VREG + Hysteresis, the charge will be
suspended (or not started, depending on the condition)
to prevent overcharging.
5.4
Preconditioning
If the voltage at the VBAT pin is less than the
preconditioning threshold, the MCP73213 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 MCP73213 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 MCP73213 device
enters the Constant Current (Fast Charge) mode.
Note:
5.4.1
The MCP73213 device also offers 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
MCP73213 device remains in this condition until the battery is removed or input power is cycled. If the battery is
removed, the MCP73213 device enters the Standby
mode, where it remains until a battery is reinserted.
Note:
The typical preconditioning timer for
MCP73213
is
32 minutes.
The
MCP73213 also offers options with no
preconditioning timer.

5.5
Constant-Current Mode - Fast
Charge
During 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:

If the internal timer expires before the recharge voltage
threshold is reached, a timer fault is indicated and the
charge cycle terminates. The MCP73213 device
remains in this condition until the battery is removed. If
the battery is removed or input power is cycled, the
MCP73213 device enters the Standby mode where it
remains until a battery is reinserted.

TIMER EXPIRED DURING
CONSTANT-CURRENT - FAST
CHARGE MODE
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 8.2V,
8.4V, 8.7V or 8.8V with a tolerance of ± 0.5%.
Where:
TABLE 5-1:
5.5.1
5.6
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 ConstantVoltage 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 the internal
timer expires. 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 MCP73213 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 MCP73213 also offers options with
no automatic recharge.
For the MCP73213 device with no recharge option, the
MCP73213 will go into Standby mode when the termination condition is met. The charge will not restart until
the following conditions have been met:
• Battery is removed from the system and inserted
again
• VDD is removed and plugged in again
• RPROG is disconnected (or high-impedance) and
reconnected

Thermal Regulation
The MCP73213 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 MCP73213 device. Refer to Section 1.0

The MCP73213 suspends charge if the die

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. A typical 25 mA
detection current is supplied for recovering from the
battery short condition.
Preconditioning mode resumes when VBAT raises
above the battery short protection threshold. The battery voltage must rise approximately 150 mV above the
battery short protection voltage before the MCP73213
device becomes operational.
The charge status outputs are open-drain outputs with
two different states: Low (L), and High-Impedance
(High 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 summarizes the state of the status outputs
during a charge cycle.

6.1
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.
6.1.1
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 the 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:
6.1.1.2
Please consult with your battery supplier
or refer to the battery data sheet for the
preferred charge rate.
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
Preconditioning mode to Constant-Current mode. In
this case, the power dissipation is:
EQUATION 6-1:
PowerDissipation =  V DDMAX – V PTHMIN   IREGMAX
Where:
VDDMAX
=
the maximum input voltage
IREGMAX
=
the maximum fast charge current
VPTHMIN
=
the minimum transition threshold
voltage
DS20002190C-page 22
Power dissipation with a 9V, ±10% input voltage
source, 400 mA ±10% and preconditioning threshold
voltage at 6V is:
EQUATION 6-2:
Power dissipation =  9.9V – 6.0V   440 mA = 1.58W
This power dissipation with the battery charger in the
DFN-10 package will result approximately 98C above
room temperature.
6.1.1.3
External Capacitors
The MCP73213 is stable with or without a battery load.
In order to maintain good AC stability in 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,
bypass
capacitance may be necessary to compensate for the
inductive nature of the battery pack.
For typical applications, it is recommended to apply a
minimum of 16V rated 1 µF to the output capacitor and
a minimum of 25V rated 1 µF to the input capacitor.

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.
6.1.1.4
Reverse-Blocking Protection
The MCP73213 provides 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.

6.2
PCB Layout Issues
For optimum voltage regulation, place the battery pack
as close as possible to the device’s VBAT and VSS pins
to minimize voltage drops along the high-currentcarrying PCB traces.
If the PCB layout is used as a heatsink, adding multiple
vias in the heatsink pad can help conduct more heat to
the backplane of the PCB, thus reducing the junction
temperature. Figures 6-4 and 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.

INCLUDING BUT NOT LIMITED TO ITS CONDITION,

arising from this information and its use. Use of Microchip
devices in life support and/or safety applications is entirely at
the buyer’s risk, and the buyer agrees to defend, indemnify and
hold harmless Microchip from any and all damages, claims,
