2.3 Device Power Supply
The PAN13x6C Bluetooth radio solution is intended to work in devices with a limited power
budget such as cellular phones, headsets, hand-
held PC’s and other battery-operated devices.
One of the main differentiators of the PAN13x6C is its power management
– its ability to draw
as little current as possible.
The PAN13x6C device requires two kinds of power sources:
1. Main power supply for the Bluetooth - VDD_IN = VBAT
2. Power source for the 1.8 V I/O ring - VDD_IO
The PAN13x6C includes several on-chip voltage regulators for increased noise immunity. The
PAN13x6C can be connected either directly to the battery or to an external 1.8-V DC to DC
converter.
