Infineon HITFET™+ - the smart protected low-side switch

The HITFET™+ family is the new portfolio of protected low-side switches based on a new technology, enabling a significant shrink with the new benchmark package TDSO-8 (up to 50% shrink compared to DPAK).

The family provides an innovative technical concept for low-side switch applications. This new portfolio offers unique features for automotive low-side switches, enabling high PWM (up to 50kHz) applications and handling high inrush current loads with current limit trigger concept.

Key features

• Low-side switches with integrated protection features
• Scalable in RDSON from 125mOhm down to 11mOhm
• Adjustable slew rate control (only BTF3xxxEJ)
• Enhanced smart current protection

Additional features

• High design flexibility
• Addressing applications with high switching speed requirements
• Driving applications with high inrush current
• Improved short circuit robustness (by min. 10x)
• Diagnosis independent from input

Applications

• Optimized for 12V automotive and industrial applications
• 12V low-side loads
• Suitable for automotive and industrial applications
• All types of resistive, inductive and capacitive loads
• Suitable for driving applications with high PWM up to 50kHz

  The BTS3xxxEJ series Demoboard is a small PCB where a sample of the BTS3xxxEJ family is already mounted. A pair of LEDs show the activation of the STATUS signal and if the surrounding circuit is supplied. The Demoboard can be use as single stand or also pin compatible with Infineon XMC1100 Boot Kit and Arduino Uno.
