Infineon Technologies AG rolls out its HITFET™+ family of protected low-side switches

Supporting the trend from relay to more robust semiconductor solutions, Infineon Technologies AG rolls out its HITFET™+ family of protected low-side switches. The HITFET+ family (High Integrated Temperature protected MOSFET) offers a compelling feature-set with its diagnosis function, digital status feedback and short-circuit robustness, and – not available until today – controlled slew rate adjustment for easily balancing switching losses and EMC compliance. The HIT-FET+ family will comprise at least 16 members varying in RDS(on) (10 to 800mOhm), feature set (i.e. with and without status feedback), and package size (D-PAK with 5 or 3 pins, DSO with 8 pins). HIT-FET+ products of one package size are completely scalable: There is no need for system designers to change either software or PCB lay-out to drive various loads. The first family member, the BTF3050TE, is already available in high-volume. HITFET+ is the right choice in a wide range of automotive and industrial applications whenever there is need for MOSFETs with protection functionality.

In automotive applications, the HITFET+ products can drive solenoids for valve control with PWM (Pulse Width Modulation) up to 20kHz. Moreover, they suit automotive light dimming applications where they prevent flickering and support the current intensities of 10W to 60W which are typical here. In addition, the HITFET+ family is suitable for a vast range of other automotive applications such as mid-size and small-size electric motor drives for door lock or parking brake; for injection valves for alternative fuel (LPG, CNG); flaps driving in HVAC (Heating Ventilation and Air-Conditioning); rear wheel steering applications as well as safety relay replacement in active suspension systems.

Also, HITFET+ products are suitable as protected drivers in a wide area of industrial applications such as printers; vacuum cleaners; solar power modules; and vending machines.
