ADVANCE INFORMATION
Diagrams below shows the typical application connections for Li-Ion battery and for the external PVDD or 3S Battery connection. SEL1 is used for HW Mode selection or I2C Mode selection of the Device.
System can use same 1.8V supply source to power the IOVDD and VDD if required. The decoupling caps C2 and C3 should still be placed close to the device pins.
VBAT, VDD, PVDD power rails are critical for device performance and wide trace should be used from the source PMIC to these pins to minimize parasitic inductance. Supply ripple should be kept at minimum for these rails and should be connected to common supply planes.
