Chapter 2. Installation and Operation

2.1 FEATURES

The MCP7386X Battery Charger Evaluation Board has the following features:

• Evaluation of MCP7386X devices in 4 x 4, 16-lead QFN packages

• Simple, stand-alone operation or microcontroller-compatible

• Powered from external bench supply or wall cube

• Surface-mount design

• Fully assembled and tested

2.2 GETTING STARTED

The MCP7386X Battery Charger Evaluation Board is a fully-functional, assembled and
tested surface-mount board for evaluation of Microchip’s MCP7386X Advanced Single
or Dual-Cell, Fully Integrated Lithium-Ion/Lithium-Polymer Charge Management
Controllers. The following steps provide simple, stand-alone operation. Refer to
Figure 2-1 for the setup configuration diagram. The setup configuration diagram
depicts evaluation of the installed MCP73861 for single-cell applications.

1. Connect an external bench supply or wall cube to the surface-mount test points
provided. The input voltage source should be in the range of 5V to 12V. Refer to
Section 2.3.1 “Input Source” for details on the input source requirements.

2. Connect a single-cell Lithium-Ion or Lithium-Polymer battery pack to the circuit
for evaluation.

3. Connect an external battery pack thermistor to the J7 (THERM) input. The
thermistor should be connected from J7 (THERM) to J6 (V

BAT

–). If continuous
cell temperature monitoring is not desired, place a 10 kΩ resistor from THERM
to V

BAT

–, or populate R5 with a 10 kΩ resistor.

4. Turn on the bench supply or plug in the wall cube.

5. A green LED (D

1

) provides status during the charge cycle. A red LED (D2)
indicates a Fault condition. Refer to the MCP73861/2/3/4 data sheet (DS21893)
for details.

Note: Observe correct polarity of connection. Positive terminal connects to J2

(V

2.3 DETAILED DESCRIPTION

The MCP7386X Battery Charger Evaluation Board is set up to evaluate simple,
stand-alone, linear charging of single/dual-cell Lithium-Ion/Lithium-Polymer battery
packs. The reference design provides constant current charging, followed by constant
voltage charging with automatic charge termination. As provided, the MCP7386X
Battery Charger Evaluation Board is set for a fast charge, constant current level of

1.2A, typical for single-cell applications. The MCP73861 is provided in a 4 x 4, 16-lead
QFN package and is equipped with shutdown control, status indicator, fault indicator,
safety timer and a continuous cell temperature monitor. For dual-cell applications, the
MCP73862 or MCP73864 can be substituted for the MCP73861. Refer to the
MCP73861/2/3/4 data sheet (DS21893) for details on the individual device features.

2.3.1 Input Source

The MCP7386X Battery Charger Evaluation Board is designed to provide a fast charge
current of 1.2A, typical. The input source should provide a voltage in the range of 5V to
12V. The input source should be capable of providing a minimum of 7.5W.

Lower peak currents can be obtained by adjusting the value of the charge programming
resistors (R

2

). A corresponding lower-power input source may then be utilized. Refer
to the MCP73861/2/3/4 data sheet (DS21893) for details on determining the
appropriate programming resistor.

2.3.2 Safety Timer Periods

The MCP7386X Battery Charger Evaluation Board can be used with a variety of battery
packs. As provided, the MCP7386X Battery Charger Evaluation Board is set up to
perform well with single-cell, 1000 mAh battery packs. Battery packs with alternative
capacities and various charge currents can be implemented. The safety timer periods
may need to be adjusted in order to ensure a full charge. The safety timer periods can
be adjusted by changing the capacitance of C

3

. Refer to the MCP73861/2/3/4 data

sheet (DS21893) for details on determining the appropriate timer capacitance.

2.3.3 Disable Control

The MCP7386X Battery Charger Evaluation Board is designed to provide stand-alone
operation. The installed MCP73861 device is enabled whenever the input source is
present. To disable charging, a jumper can be placed between J1, EN and J3 (V

IN

–).

2.3.4 Battery Headers

Independent battery connections are provided. The battery pack positive terminal
should be connected to J5 (V

BAT

+). The battery pack negative terminal should be

connected to J6 (V

BAT

–). In addition, a connection is provided for a nominal 10 kΩ at
+25°C NTC thermistor, situated in the battery pack for temperature sensing. When the
cell temperature is between -5°C and +55°C, installed resistors provide a charging
window when a thermistor with a sensitivity index (β) of 3982 is utilized. Charging is
inhibited when the cell temperature deviates outside the preset window. The resistor
values can be adjusted to provide the desired charging window for a variety of
thermistors. Refer to the MCP73861/2/3/4 data sheet (DS21893) for details.

2.3.5 Device Support Options

The MCP7386X Battery Charger Evaluation Board supports the entire MCP7386X
family. The MCP7386X Battery Charger Evaluation Board is provided with one
reference design utilizing the MCP73861. Alternate devices can be substituted in
order to evaluate the different MCP7386X family options.

2.3.6 Microcontroller Option

Connection points provide easily-accessible locations for interface to a host
microcontroller. The host microcontroller can be used to disable the charger, monitor
charge status or terminate a charge.

2.3.7 Output Voltage Options

The MCP7386X Battery Charger Evaluation Board is provided with a
Constant-Voltage mode output voltage of 4.2V per cell, the evaluation of which can be
achieved by moving resistor R

4

to R3, or by shorting the R3 pads.

Note: Improper connection of the battery may result in damage to the battery

and increase the possibility of personal injury. It is also important to avoid
shorting the battery terminals together.
