RHRPM4424 Rad-hard 4.5 A dual low-side MOSFET driver Datasheet - preliminary data Applications Switch mode power supply DC-DC converters Motor controllers Line drivers FLAT-16 FLAT-10 Description The RHRPM4424 is a flexible, high-frequency dual low-side driver specifically designed to work Features with high capacitive MOSFETs and IGBTs in an Wide operating voltage range: 4.65 V to environment with high levels of radiation such as 18 V aerospace. The RHRPM4424 outputs can sink Parallel driving capability up to 9 A and source 4.5 A of peak current independently. Non-inverting configuration By putting in parallel the two PWM outputs, a higher driving current (up to 9 A peak) can be Input 5 V logic level compatibility obtained. The RHRPM4424 works with 110 ns typical propagation delay CMOS/TTL compatible PWM signal so it can be Matched propagation delays between the driven by an external PWM controller, such as two channels (5 ns max.) the ST1843 or the ST1845. The FLAT-16 version 20 mV maximum low level output voltage conforms to an industry standard pinout and can 30 ns rise and fall times dissipate up to 550 mW per channel, while +/-5 V common mode bouncing between FLAT-10 version optimizes the PCB real estate. signal and power grounds Since both of packages are hermetic, this device TID: is suitable for any kind of harsh-environment. 100 krad HDR 100 krad LDR QML-V qualification planned Hermetic package Table 1: Device summary SMD Max. power Mass Temperature Order code Quality level EPPL Package (1) pin dissipation mW g range (2)(3) RHRPM4424K01V QML-V (2)(3) RHRPM4424K02V FLAT-16 550 - - 0.7 -55 to 125 C (3) RH-PM4424K1 Engineering (2)(3) model RH-PM4424LK1 FLAT-10 350 Notes: (1) Per channel at T = 70 C a (2) Under development.
