Description

The MADR-010574 switch driver is designed to work

with M/A-COM Technology Solutions high power

and high voltage PIN diodes. This driver consists of

two independently controlled drivers which are able

to provide 200 mA series / 50 mA shunt current to a

series/shunt, series/shunt SPDT PIN diode switch.

The back bias voltage is configurable from 20 V to

250 V. High voltage level shifters are integrated so

that it can be easily controlled by 3 V or 5 V CMOS

logic. While consuming low quiescent current, this

driver has a typical delay of less than 8 µs when

driving 220 pF capacitor load. If needed, the

switching speed can be improved by consuming

more quiescent power.

This driver is packaged in a lead free 7 mm PQFN-

16LD package and is available in tape and reel

packaging for high volume applications.

1. The paddle of the QFN package should be tied to ground.

2. N/C pins (except Pin 15) can be grounded. The clearance

from high voltage pins should be at least 0.8 mm. Pin 15

must be left open.
