Power MOSFETs for motor drives
17 March 2010
Power Electronics / Power Management
International Rectifier has launched a family of HEXFET power MOSFETs with low on-state resistance for DC motor drive applications.
The parts are available in a 5 x 6 mm PQFN package with optimised copper clip and solder die. The IRFH6200TRPbF 20 V device delivers RDS(on) of only 1,2 mΩ at 4,5 V VGS to cut conduction losses for DC motor drive applications such as hand tools. The 25 V IRFH5250TRPbF and 30 V IRFH53xxTRPbF are designed for DC switch applications such as active ORing and DC motor drive applications requiring high current carrying capability and high efficiency. The IRFH5250TRPbF features RDS(on) of 1,15 mΩ combined with just 52 nC gate charge, while the IRFH5300TRPbF delivers RDS(on) of only 1,4 mΩ combined with 50 nC gate charge.
All of the devices feature low thermal resistance (less than 0,5°C/W), are MSL1 industrial-qualified and RoHS compliant, containing no lead, bromide or halogen.
