Description
HEXFET
®
power MOSFETs from International Rectifier
utilize advanced processing techniques to achieve ex-
tremely low on-resistance per silicon area. This benefit,
combined with the ruggedized device design, that Inter-
national Rectifier is well known for,
provides the de-

signer with an extremely efficient and reliable device
for use in battery and load management.
The TSSOP-8 package has 45% less footprint area than
the standard SO-8. This makes the TSSOP-8 an ideal
device for applications where printed circuit board space
is at a premium. The low profile (<1.2mm) allows it to fit
easily into extremely thin environments such as portable
electronics and PCMCIA cards.
