• Manufacturer Part Number: SI3220PPT-EVB
• Description: EVALUATION BOARD FOR THE Si3220 DUAL PROSLIC
• Manufacturer: SILABS [Silicon Laboratories]

* Optional protection devices:
Battery tracking over voltage protection devices are required when using maximum battery voltage on Si3200.
Fixed voltage thyristor protection devices, D3, D4, D13, D14 can be used in certain cases. The selection of the thyristor
device voltage depends on the required battery voltage for ringing. The maximum clamp voltage for the device must be
under the Si3200 maximum voltage. The minimum clamping voltage of the device must be above the maximum battery
voltage. For example, the Teccor P0901SC is shown for applications that operate from a maximum negative battery of
-72V.
Over current devices should be selected for application requirements and over voltage protection device current limitations.
