Optimising design of dc fans and inverters

A range of four H-bridge mosfet packages from Diodes Incorporated has been designed to simplify dc fan and ccfl inverter circuits, by reducing both component count and pcb size in space constrained applications.

Featuring dual complementary pairs of N- and P-type mosfets in an SO8 package, the zxmhc parts will replace either four discrete SOT23 packaged mosfets or two SO8 complementary mosfet packages. Two 30V H-Bridges, the ZXMHC3A01N8 and ZXMHC3F381N8, are suitable for 12V dc fan and inverter applications. The 60V rated ZXMHC6A07N8 and 100V rated ZXMHC10A07N8 are targeted at 24V dc and 48V dc motor control circuits respectively.
