HITFET™+ 24V | automotive smart low-side switches
Smart low-side power switches with diagnostics for 24V automotive and industrial applications
HITFET™+ 24V is Infineon's latest generation of highly integrated, temperature-protected switches for automotive and industrial applications with a significant size shrink compared to the existing Classic HITFET™ 12V portfolio (up to 50 percent). This family supports fast switching up to 20 kHz with an RDS(on) range from 16 mΩ to 50 mΩ in TDSO-8 packages.
- RDS(on) range 16-50 mΩ
- Up to 36 V operating voltage
- One channel
- Automotive qualified, AEC-Q100
- PWM up to 20 kHz
- Current limitation
- Basic self-protection & diagnosis
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™+ 12V portfolio comprises single-channel devices with an RDS(ON) 16 mΩ or 50 mΩ and nominal current from 4 A or 7 A in a TDSO-8 package. The family supports fast-switching applications with PWM 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 online simulations available on each product page in the "Design Support" section. In addition, we offer a dedicated tool suite for smart power switches and gate driver ICs for automotive power distribution.
Infineon’s smart power switches & gate driver tool suite supports system architects and hardware designers from idea to 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 different “Simulation & Modeling” tools, various application scenarios can be simulated for the respective product. The results can be documented in the report tool and verified with the “Configuration” tools plus the corresponding evaluation boards.
