Test conditions:
1. “*” means under development.
2. The total capacitors of VBAT net are not less than 420uF.
3. The data in Table 6 and Figure 4 is TBD.
To decrease the voltage dropping, make sure the VBAT voltage no less than 3.135V. The following figure
shows the reference circuit of power supply for the VBAT.

In this reference circuit, some multi-layer ceramic chip (MLCC) capacitors (0.1/1uF) with low ESR in high
frequency band can be used for EMI suppression.
These capacitors should be put as close as possible to VBAT pins. Also, users should keep VBAT trace on
