This chapter covers the test setups and tests performed, in evaluating the EVM.
• 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.
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 V
DC
.
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.
