APPLICATION INFORMATION
TVC voltage-limiting application
For the voltage-limiting configuration, the common GATE input must be connected to one side (A or B) of any
one of the transistors (see Figure 3). This connection determines the V
BIAS
input of the reference transistor. The
V
BIAS
input is connected through a pullup resistor (typically, 200 k
) to the V
DD
supply. A filter capacitor on V
BIAS
is recommended. The opposite side of the reference transistor is used as the reference voltage (V
REF
)
connection. The V
REF
input must be less than V
DD
– 1 V to bias the reference transistor into conduction. The
reference transistor regulates the gate voltage (V
G
) of all the pass transistors. V
G
is determined by the
characteristic gate-to-source voltage difference (V
GS
) because V
G
= V
REF
+ V
GS
. The low-voltage side of the
pass transistors has a high-level voltage limited to a maximum of V
G
– V
GS
, or V
REF
.
