3.2 Power Supply
BGS5 needs to be connected to a power supply at the SMT application interface (2 lines each
BATT+ and GND).
The power supply of BGS5 has to be a single voltage source at BATT+. It must be able to pro-
vide the peak current during the uplink transmission.
All the key functions for supplying power to the device are handled by the power management
section of the analog controller. This IC provides the following features:
• Stabilizes the supply voltages for the baseband using low drop linear voltage regulators and
a DC-DC step down switching regulator.
• Switches the module's power voltages for the power-up and -down procedures.
• SIM switch to provide SIM power supply.
