Selecting a SiBOD Device
1. When selecting a device, it is important
that the VRM of the device be equal to or
greater than the operating voltage of the
system. For example, when protecting
the ringing circuit of a telephone handset,
SiBOD VRM > VDC + RINGING VOLTAGE
SiBOD VRM > VDC + V√ 2X RINGING VOLTAGE
2. The minimum holding current (IH) of the
device must be carefully selected if the
SiBOD is to reset after diverting a surge.
The minimum IH value of the SiBOD must
be greater than the current the system is
capable of delivering, otherwise the
device will remain conducting following
a transient condition.
