General Description
The HV3922 is a monolithic, high voltage quad-output driver that is
designed to be used in conjunction with the Supertex VN2222NC, a
separate N-channel DMOS FET quad array, whose device characterics
are briefly described below. Together, these devices per-form a 220V push-
pull function that is especially suited for driving PIN diodes in applications
such as frequency-hopping radios, microwave communication systems
and phased array radar.
Used as a microwave or RF switch, the HV3922 has 4 high voltage P-
channel outputs: PD0, PD1, PD2 and PD3. Additional controls are Chip
Select (CS) and Output Enable (OE) functions. The HV3922 also has an
output fault detection function that protects the outputs from damage by
putting them into a high impedance state when a short is detected. The
HV3922 provides 4 low voltage outputs - DRV0, DRV1, DRV2 and DRV3
- that drive the gates of the 4 N-channel FETs.
The VN2222NC is an N-channel DMOS FET quad array recommended
for use in conjunction with HV3922 outputs to form four 220V push-pull
outputs. Each of the four devices has a max R
5.0 amps, and BV
