PRODUCTION DATA.
Power supply decoupling for the gas gauge requires a pair of 0.1-μF ceramic capacitors for (PBAT) and (VREG25) pins. These should be placed reasonably close to the IC without using long traces back to VSS. The LDO voltage regulator, whether external or internal to the main IC, requires a 0.47-μF ceramic capacitor to be placed fairly close to the regulation output pin. This capacitor is for amplifier loop stabilization and as an energy well for the 2.5-V supply.
