About HITFET™ + 24V automotive smart low-side switches

Infineon's HITFET™ + 24V smart low-side switches are qualified and optimized for 24 V automotive – more specifically commercial, construction, and agricultural vehicles (CAV) – and industrial applications such as power steering systems, motor control, lighting, HVAC systems, and power distribution. The HITFET™ + 24V family offers single-channel devices with up to 50% shrinkage and better short-circuit robustness, among other additional and improved features compared to its predecessor family, Classic HITFET™ 24V.

HITFET™ + 24V devices offer an integrated protection function that safeguards against overcurrent, overtemperature, and short-circuit events. All HITFET™ + 24V devices have a latch thermal shutdown function, in which case a restart must be performed by the MCU. The overvoltage protection can be activated during load dump or inductive turn-off. Moreover, HITFET™ + 24V switches can drive applications with high switching speed requirements and have a dedicated STATUS signal for offering digital diagnosis.

HITFET™ + 24V automotive smart low-side switches product family

The HITFET™ + 24V portfolio comprises single channel variants which range from 16 mΩ to 50 mΩ with nominal current from 4 A to 7 A in TDSO-8 package. This family support fast switching applications up to 20 kHz.

HITFET™ + 24V design support

Infineon offers a range of design-in materials, which include application notes, evaluation boards, PCB design data, simulation models and also online simulations. Those materials could be found on the each product page in chapter "Design Support".  In addition, we offer a dedicated tool suite for Smart Power Switches and Gate Driver IC's for automotive power distribution.

Infineon Smart Power Switches & Gate Driver Tool Suite supports system architects and hardware designers from the idea to the realization. This suite allows the user to select the right smart power switch or gate driver IC for a specific load using one of the “Finder & Selection” tools. Together with the different “Simulation & Modeling” tools, various application scenarios can be simulated for the respective product. The results can be document in the report tool and verified with the “Configuration” tools plus the corresponding evaluation boards.
