Operating Characteristics

4.1. Power Supply

Power supply pin and ground pins of the module are defined in the following table.

Table 23: Pin Definition of Power Supply and GND Pins

4.1.1. Reference Design for Power Supply

The module is powered by VBAT, and it is recommended to use a power supply chip that can provide at
least 0.5 A output current. For better power supply performance, it is recommended to parallel a 22 μF
decoupling capacitor, and two

filter capacitors (1 μF and 100 nF) near the module’s VBAT pin. In addition,

it is recommended to add a TVS near the VBAT to improve the surge voltage bearing capacity of the

module. In principle, the longer the VBAT trace is, the wider it should be.

VBAT reference circuit is shown below:
