IRS44273L
25 V single-channel low-side gate driver IC
EiceDRIVER™ 25 V single-channel, low-side gate driver IC with typical 1.5 A source and 1.5 A sink currents in 5-lead SOT23 package for MOSFETs and IGBTs. IRS44273 can also be used in conjunction with IPMs, such as IFCM10S60GD, which integrate a PFC IGBT but no PFC gate driver IC.
The proprietary latch immune CMOS technologies enable ruggedized monolithic construction. The logic inputs are compatible with standard CMOS or LSTTL output. The output drivers feature a current buffer stage.
EVAL-M3-TS6-665PN is an evaluation board for motor drives applications. It integrates a single-phase PFC and 3 phase inverter. IRS44273L is featured in the PFC stage with discrete IGBT IKB20N65H5. The board can be combined with one of the available MADK control board like EVAL-M3-102T to demonstrate Infineon’s motion control IC and discrete technology for motor drive applications.
REF-SHA35WRC2SYS is a full-featured high voltage ceiling fan reference design. The main board includes IMD112T iMOTION™ driver which provides turnkey PFC and motor control with the field-proven MCE (Motor Control Engine), that eliminates software coding from the ceiling fan motor control algorithm development process. It includes the IRS44273L for the PFC gate driver IKA08N65H5 DuoPack IGBTs and didoes for PFC switching, and the TRENCHSTOP(TM) RC-Series IKN03N60RC2 that provides cost-effective, monolithically integrated IGBTs with diode for the inverter stage.
