Infineon Technologies recently announced the HITFET+ family of protected low-side switches. The HITFET+ family (High Integrated Temperature protected MOSFET) offers a handy feature-set with its diagnosis function, digital status feedback and short-circuit robustness, and controlled slew rate adjustment for easily balancing switching losses and EMC compliance. The HITFET+ family will comprise at least 16 members varying in R DS(on) (10 to 800 MΩ), feature set (i.e., with and without status feedback), and package size (D-PAK with 5 or 3 pins, DSO with 8 pins). HITFET+ products of one package size are completely scalable. You don’t need to change either software or PCB layout to drive various loads. The BTF3050TE is already available in high-volume.
HITFET+ products are suitable as protected drivers in industrial applications, including solar power modules, printers, and vending machines.
As for use in automotive systems, the HITFET+ products can drive solenoids for valve control with PWM up to 20 kHz. They are also a good fit for automotive light-dimming applications. In addition, the HITFET+ family can be useful in a variety other automotive applications, such as the following:
- mid-size and small-size electric motor drives for door locks or a parking brake
- injection valves for alternative fuel (LPG, CNG)
- flaps driving in HVAC
- rear wheel steering applications
The BTF3050TE is now available in a lead-free TO-252 package (D-PAK 5-pin) in high volume. Additional HITFET+ products are scheduled to be released toward the end of 2015.
