H-bridges for motor control circuits

19 August 2009 Power Electronics / Power Management

A new range of four H-bridge MOSFET packages from Diodes Incorporated has been rolled out to simplify DC motor control circuits, by reducing both component count and PCB size in space constrained fan and CCFL inverter applications.

Featuring dual complementary pairs of N- and P-type MOSFETs in an SO8 package, the ZXMHC parts can replace either four discrete SOT23 packaged MOSFETs or two SO8 complementary MOSFET packages. Two 30 V H-bridges, the ZXMHC3A01N8 and ZXMHC3F381N8, suit 12 V d.c. applications and offer users a choice of low RDS(ON) performance. The 60 V rated ZXMHC6A07N8 and 100 V rated ZXMHC10A07N8 are targeted at 24 V d.c. and 48 V d.c. motor control circuits respectively.
