Provided in the SM8 package, the ZXMHC6A07T8 MOSFET H-bridge from Zetex reduces board space and simplifies design in motor drive applications.

Provided in the SM8 package, the ZXMHC6A07T8 mosfet H-bridge from Zetex reduces board space and simplifies design in motor drive applications.

The low gate charge of the copackaged N- and P-channel trench mosfets, coupled with on-resistances of just 0.3 and 0.425ohm, respectively, and a 60V breakdown capability, makes the device easy to drive and removes the need for buffering.

By replacing four discrete mosfet component placements with one, the H-bridge chip saves significant PCB space.

The compact SM8 package occupies a maximum area of just 7.3 x 6.7mm.

The proprietary lead frame design of the SM8 package provides a low thermal resistance of 56C/W that allows for cool running and results in a power dissipation of 2.25W and an output current up to 2.2A.
