A second lower battery voltage may be connected to the device at terminal
reduce short loop power dissipation.
The SLIC automatically switches between the two battery supply voltages without need
for external control. the silent battery switching occurs when the line voltage passes the
value |VB2| - 40
For correct functionality it is important to connect the terminal
supply via the diode
terminal VB and the VB2 power supply, see

The PBL 38640/2 SLIC has got a receive interface at the four- wire side which makes it
possible to reduce the number of capacitors in the applications and to fit both single and
dual battery feed CODECs. The RSN terminal, connecting to the CODEC receive output
via the resistor
currents floating due to DC voltage differences between RSN and the CODEC output
without using any capacitors. This is done by connecting a resistor
