Description

The RHRPM4424 is a flexible, high-frequency dual low-side driver specifically

designed to work with high capacitive MOSFETs and IGBTs in an environment with

high levels of radiation such as aerospace. The RHRPM4424 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. The RHRPM4424

works with CMOS/TTL compatible PWM signal so it can be driven by an external

PWM controller, such as the ST1843 or the ST1845. The FLAT-16 version conforms

to an industry standard pinout and can dissipate up to 550 mW per channel, while

FLAT-10 version optimizes the PCB real estate. Since both of packages are hermetic,

this device is suitable for any kind of harsh-environment.

Applications

? Switch mode power supply

? DC-DC converters

? Motor controllers

? Line drivers
