DESCRIPTION
This Power MOSFET is the latest dev elo pment of
STMicroelectronis unique "Single Feature Size™"
strip-based process. The resulting transistor
shows extremely high packing density for low onresistance, rugged avalanche characteristics and
less critical alignment steps therefore a remarkable manufacturing reproducibility.
APPLICATIONS
■ DC MOTOR DRIVE
■ DC-DC CONVERTERS
■ BATTERY MANAGEMENT IN NOMADIC
EQUIPMENT
■ POWER MANAGEMENT IN
PORTABLE/DESKTOP PCs
