Description

The RHFPM4424 is a flexible, high-frequency

dual low-side driver specifically designed to work

with high capacitive MOSFETs and IGBTs in a

high radiation environment such as the

aerospace.

Features

• Wide operating voltage range: 4.5 V to 18 V

• Parallel driving capability up to 9 A

• Non-inverting configuration

The RHFPM4424 outputs can sink and source 4.5

A of peak current independently. By putting in

parallel the two PWM outputs, a higher driving

current (up to 9 A peak) can be obtained.

• Input 5 V logic level compatibility

• 110 ns typical propagation delay

• Matched propagation delays between the two

The RHFPM4424 works with CMOS/TTL

channels (5 ns max.)

compatible PWM signal so it can be driven by an

external PWM controller, for instance the ST1843

or the ST1845. The hermetic FLAT-16 version has

an industry standard pinout and it can dissipate

up to 1.5 W (750 mW per channel), while FLAT-10

version optimizes the PCB real estate. Both of

packages are hermetic, making the device well-

suited for any kind of harsh environment.

• 20 mV maximum low level output voltage

• 30 ns rise and fall times

• +/-5 V common mode bouncing between signal

and power grounds

• TID:

– 300 krad HDR

– 100 krad LDR

• QML-V qualification planned

• Hermetic package
