Design Requirements

For this design example, use the parameters listed in Table 2.

Table 2. Design Parameters

PARAMETER EXTERNAL COMPONENT NOTE
BAT and PACK Filters Rfilter and Cfilter Recommended to use 100 Ω and 0.01 µF.
VDDCP capacitor CVDDCP A minimum of 470 µF is required. A higher value can be used to support higher-loading capacitance. See Recommended Implementation and bq76200 Application Note () for details.
PACKDIV resistor divider Ra and Rb Based on the max PACK voltage of the application, calculate the total value of (Ra + Rb) that can keep the PACKDIV current below 500 µA.
CHG, DSG, PCHG gate-source resistor Rgs Recommended to use 10 MΩ. A different Rgs value may change the loading level of the charge pump. System designer should perform thorough system testing if a different Rgs is used.
