When generating a high-voltage ringing amplitude using
the Si3220, the power dissipated during the OHT state
typically increases due to operating from the ringing
battery supply in this mode. To reduce power, the
chipset provides the ability to accommodate up to three
separate battery supplies by implementing a secondary
battery
switch
using
a
few
low-cost
external
components as illustrated in Figure 20.
The Si3220’s BATSEL pin is used to switch between the
VBHI (typically –48 V) and VBLO (typically –24 V) rails
using the switch internal to the Si3200/2. The Si3220’s
GPO pin is used along with the external transistor circuit
to switch the VBRING rail (the ringing voltage battery rail)
onto the Si3200/2’s VBAT pin when ringing is enabled.
The GPO signal is driven automatically by the ringing
cadence provided that the RRAIL bit of the RLYCON
register is set to 1 (signifying that a third battery rail is
present).
