Micro8

™ devices are an advanced series of power MOSFETs

which utilize Motorola’s High Cell Density HDTMOS process to

achieve lowest possible on–resistance per silicon area. They are

capable of withstanding high energy in the avalanche and commuta-

tion modes and the drain–to–source diode has a very low reverse

recovery time. Micro8

™ devices are designed for use in low voltage,

high speed switching applications where power efficiency is important.

Typical applications are dc–dc converters, and power management in

portable and battery powered products such as computers, printers,

cellular and cordless phones. They can also be used for low voltage

motor controls in mass storage products such as disk drives and tape

drives. The avalanche energy is specified to eliminate the guesswork

in designs where inductive loads are switched and offer additional

safety margin against unexpected voltage transients.
