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 VBIAS input of the reference transistor. The
VBIAS input is connected through a pullup resistor (typically, 200 k ) to the VDD supply. A filter capacitor on VBIAS
is recommended. The opposite side of the reference transistor is used as the reference voltage (VREF)
connection. The VREF input must be less than VDD – 1 V to bias the reference transistor into conduction. The
reference transistor regulates the gate voltage (VG) of all the pass transistors. VG is determined by the
characteristic gate-to-source voltage difference (VGS) because VG = VREF + VGS. The low-voltage side of the
pass transistors has a high-level voltage limited to a maximum of VG – VGS, or VREF.
