HITFET™:
Low-Side Protected Switches
HITFET™ provides a high level of protection for
overtemperature, short-circuit, overcurrent,
overvoltage, open-load and ESD-sensitive circuits.
HITFET™ combines all these protection features
in one easy-to-use device.
Infineon has recently expanded its HITFET™ portfolio
with the new product BTF3050TE.
