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.
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

.
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
charge the same numbers of cells as the evaluated (see
Set up the EVM as shown in
. 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
