Page 6: Test Summary
www.ti.com Test Summary Test Summary This section covers the test setups and tests performed in evaluating the EVM. Equipment • Power Source: Current-limited, 15-V laboratory power 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. - Page 7 www.ti.com Test Summary 3. The bq2412x enters preconditioning mode if the battery is below the V threshold. In this mode, (LOWV) the bq2412x precharges the battery with a low current programmed by the ISET2 pin. If the R SET1 resistors are the same value, then the precharge is 1/10th the fast-charge current (I SET2 PRE-CHG 1.33 A/10 = 133 mA) until the battery voltage reaches the V...
