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 espe-

cially suited for driving PIN diodes in applications such as fre-

quency-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 in the VN2222NC device. See

the diagram below for an example of the push-pull output struc-

ture that these two devices provide.

For detailed electrical characteristics of the VN2222NC, please

see the data sheet in Chapter 8. Currently, the HV3922 is

available in through-hole and surface-mount ceramic packages

that are suitable for military applications, while the VN2222NC is

offered in ceramic quad and discrete packages (VN2224N2 and

VN2224N3). For commercial product availability, please consult

the factory.

Push-Pull Configuration

* VN2222NC is an N-channel DMOS FET quad array recommended for use in

conjunction with HV39 outputs to form four 220V push-pull outputs. Each of the

four devices has a max RDS(ON) of 1.25Ω, min ID(ON) of 5.0 amps, and BVDSS

of 220V.
