Introduction
This user's guide describes the bq241xxEVM (bqSWITCHER™) Evaluation Module. The Evaluation
Module provides a convenient method for evaluating the performance of a charge management solution
for portable applications using the bq241xx product family. A complete designed and tested charger is
presented. The charger is designed to deliver up to 2.0 A of continuous output current. The charger is
programmed from the factor to deliver 1.33 A of charging current. Follow the instructions in this user's
guide that pertain to the specific bq241xxEVM (one-, two- or three-cell) to be evaluated. See the
bqSWITCHER data sheet (SLUS606) prior to evaluation for detailed information on the bqSWITCHER
device.
1.1
Background
The bqSWITCHER series are highly integrated Li-Ion and Li-Pol switch-mode charge management
devices targeted at a wide range of portable applications. The bqSWITCHER series offer integrated
synchronous PWM Controller and PowerFETs, high-accuracy current and voltage regulation, charge
conditioning, charge status, and charge termination, in a small thermally enhanced QFN package. The
system-controlled version provides additional input for full charge management under system control.
The bqSWITCHER charges the battery in three phases: conditioning, constant current, and constant
voltage. Charge is terminated based on user-selectable minimum current level. A programmable charge
timer provides a backup safety for charge termination. The bqSWITCHER automatically restarts the
charge if the battery voltage falls below an internal threshold. The bqSWITCHER automatically enters
sleep mode when VCC supply is removed.
1.2
Performance Specification Summary
This section summarizes the performance specifications of the EVM. Table 1 gives the EVM performance
specifications. The TS pin has been disabled, for easier charging evaluation, by fixing its voltage to a set
value. See the EVM schematic (Figure 1) and data sheet (SLUS606) for information on how to change
R10 and R11 values to use with an external thermistor

Test Summary
This chapter covers the test setups and tests performed, in evaluating the EVM.
2.1
Equipment
•
•
2.2
Power Source: Current limited 15 V lab supply with its current limit set to 25% above the programmed
charging current (1.7 A for setup from factory). This is basically a safety limit. The actual DC input
current should be less than the charging current.
Two Fluke 75: (optional) To measure input and output voltage and drop across current sense resistor.
Setup
The bq241xx EVM board requires a regulated supply approximately 0.3 V minimum above the regulated
voltage of the battery pack (1-cell pack: 4.2 V; 2-cell pack: 8.4 V; 3-cell pack: 12.6 V) to a maximum input
voltage of 16 VDC.
A one- to three-cell battery pack is needed for EVM evaluation. The EVM should be chosen and set up to
charge the same numbers of cells as the evaluated (see Table 2).
Set up the EVM as shown in Table 2. Preset the input supply to the desired voltage, turn off supply, and
finally connect supply to J1. Set the supply's current limit 25% above the programmed charging current.
The test setup connections and jumper setting selections are configured for a stand-alone evaluation and
can be changed to interface with external hardware such as a microcontroller. See the EVM schematic
(Figure 1) and data sheet (SLUS606) for functional information on other optional connections.

R5 and R7 can be changed to regulate output between approximately 3.2 V to 15.5 V. Adjust the input voltage as required.
Output set to operate at 4.2 VDC from the factory.
To operate as a two cell version (8.4V), replace battery with a two-series cell pack, set J10 to High and adjust the Input voltage
between 9.2 V to 16 V.
Test Procedure
Set up the evaluation board as described above, by making the necessary I/O connections and jumper
selections.
WARNING
Prior to test and evaluation, it is important to verify that the EVM
selected is set up correctly for the battery pack to be charged;
several evaluation modules have a CELLs option that can be
programmed for two different size – number of series cells. TI
highly recommends that the battery pack to be charged, has
internal protection as a safety backup.
1. Apply power to the board with the power supply, preset to the suggested value in Table 2, and use
approximately 1.7 A for the current limit setting.
2. The PG LED and STAT1 should light, if the battery is charging.
3. The bq241xx enters pre-conditioning mode if the battery is below the V(LOWV) threshold. In this mode,
the bq241xx pre-charges the battery with a low current programmed by the ISET2 pin. If the RSET1 and
RSET2 resistors are the same value then the precharge is one tenth the fast charge current (IPRE-CHG =
1.33 A/10 = 133 mA) until the battery voltage reaches the V(LOWV) threshold or until the precharge timer
expires. If the timer expires then the charge current is terminated and the bq241xx enters fault mode.
STAT1 and STAT2 (if available) LEDs go dark when in fault mode.
Note:
There are several non-charging modes that share this status state. Toggling input power or
battery replacement resets fault mode.
4. Once the battery voltage is above the V(LOWV) threshold, the battery enters fast charge mode. This
EVM is programmed for approximately 1.3 A of fast charging current. The PG and STAT1 LEDs should
be on.
5. Once the battery reaches voltage regulation (4.2 V) the current tapers down as the battery reaches its
full capacity. The PG and STAT1 LEDs should light.

Test Summary
6. When the current reaches the taper termination threshold, set by the RSET2 resistor, the charge is
terminated. The PG LED should be still lit and the STAT1 LED should turn off and STAT2 LED lights.
7. If the battery discharges down to the recharge threshold, the charger starts fast charging. The PG LED
should remain lit, the STAT2 LED should turn off and STAT1 LED lights.
An alternative method of testing the EVM is with a source meter, that can sink or source current. This can
easily be adjusted to test each mode, in place of a battery.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask
work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services
are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such
products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under
the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an
unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties
may be subject to additional restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service
voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business
practice. TI is not responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would
reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement
specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications
of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related
requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any
applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its
representatives against any damages arising out of the use of TI products in such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is
solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in
connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products
are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any
non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
