Description
TIP Output.
Connect to the TIP lead of the subscriber loop.
No Internal Connection.
Do not connect to any electrical signal.
RING Output.
Connect to the RING lead of the subscriber loop.
Operating Battery Voltage.
Si3200/2 internal system battery supply. Connect SVBATa/b pin from
Si3220/25 and decouple with a 0.1 µF/100 V filter capacitor.
High Battery Voltage.
Connect to the system ringing battery supply. Decouple with a 0.1 µF/100 V
filter capacitor.
Low Battery Voltage.
Connect to lowest system battery supply for off-hook operation driving short
loops. An internal diode prevents leakage current when operating from
V
Ground.
Connect to a low-impedance ground plane.
Supply Voltage.
Main power supply for all internal circuitry. Connect to a 3.3 V or 5 V supply.
Decouple locally with a 0.1 µF/10 V capacitor.
Battery Voltage Select.
Connect to the BATSEL pin of the Si3220 or Si3225 through an external
resistor to enable automatic battery switching. No connection is required
when used with the Si3225 in a single battery system configuration.
