1-1 Introduction This user ’ s guide describes the bq2400x Evaluation Module (SLUP051). The EVM conveniently evaluates a linear Li-ion bq2400x charge-management solution for one- and two-cell battery-pack applications. This guide describes a complete designed-and-tested charger , which delivers up to 1.
Background 1-2 1.1 Background The bq2400x series ICs are advanced Li-Ion linear charge management devices for highly integrated and space-limited applications.

Setup 2-2 2.1 Setup The bq2400X EVM board requires a DC power source to provide input power and a single-cell lithium-ion or lithium-polymer battery to charge. Note: Other versions of the bq2400x IC can charge two-cell battery packs. The test setup connections and jumper setting selections are listed below .
T est Procedures 2-3 T est Summary Note: V I for a single cell should not exceed 5.3 VDC for the 1-A charge rate and 7.6 V for the .5-A charge rate. Adjust the input power supply for 5 V . The red LED should illuminate to indicate charging, unless there is a fault or the battery is fully charged.
T est Procedures 2-4 The bq2400x enters preconditioning mode if the battery is below the LowV threshold. In this mode, the bq2400x trickle-charges with approximately 65 mA for approximately 23 minutes. If the battery does not reach the LowV threshold after this period, then the charge current is terminated and the bq2400x enters fault mode.
