3.5. Power Supply
3.5.1. Power Supply Pins
BG96 provides the following four VBAT pins for connection with anexternal power supply. There are two
separate voltage domains for VBAT.
 Two VBAT_RF pins for module’sRF part.
 Two VBAT_BB pins for module’s baseband part.
The following table shows the details of VBAT pins and ground pins.

3.5.2. Decrease Voltage Drop
The power supply range of the module is from 3.3Vto4.3V. Please make sure that the input voltage will
never drop below 3.3V.The following figure shows the voltage drop during burst transmission in 2G
network. The voltage drop will be less in LTE CatM1 and LTE CatNB1 networks.
