87 / 111 page  9 Application and Implementation Note Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 9.1 Application Information The BQ2573xEVM evaluation module (EVM) is a complete charger module for evaluating the BQ25730. The application curves were taken using the BQ2573xEVM. As shown in Figure 9-1, at the charger VSYS terminal, a minimum 7-μF effective MLCC capacitance (7 × 10-μF 0603 package MLCC) is suggested for a 45-W to 65-W adapter, and two more 10-μF MLCC capacitors are needed when power reaches 90 W. Overall 50-μF effective capacitance on VSYS net is necessary (POSCAP is preferred). These capacitors do not have to be placed at the charger VSYS output terminal; all capacitors connected to VSYS net can be counted including the input capacitor of the next stage converters. 9.2 Typical Application BQ25730 ACN VBUS HIDRV1 SRN IADPT IBAT PSYS VBUS HIDRV2 SRP BATDRV VDDA COMP1 COMP2 3.3V or 1.8V CELL_BATPRES PROCHOT ACP SYS Host (I2C) Q1 Q2 Q3 Q4 REGN PGND ILIM_HIZ RAC=5m m 2.2–3.3uF 1uF REGN 10 10k 10k 10k 10k 100pF 100pF 30k VDDA 250k 350k 10 10 220k 380k To Host 47nF 47nF 1.0uF 0.1uF 6x10uF 1uF 10k RSR=5m m 1nF 33nF 33nF 3.3V or 1.8V 191k 7x10uF 40.2k 33pF 4.7nF 15k 680pF 15pF 4.7uH 10nF 1x33uF (Optional) VSYS 2x33uF 2x10uF BATT (1-5s) 10nF Figure 9-1.
