HITFET™ low-side switches offer a compelling feature set with its protection against over temperature, short circuit and overload conditions as well as ESD robustness.
The HITFET™ family can be scaled in RDS(on) and packages, as well as in feature set, e.g. diagnosis or latch and restart protection behavior. This scalability enables easy drop in replacements on short notice. “Wherever you need a MOSFET with built in protection a HITFET™ is the right choice!“
Infineon has recently expanded its HITFET™ portfolio with the new product BTF3050TE. The BTF3050TE is designed to serve the automotive and industrial low-side switch market. The 50 mOhm part can drive loads at 3A nominal and provides a very robust short circuit protection, as well as logic pin which enables a slew rate adjustment and a logic feedback which also works during PWM operation.
