Classic HITFET™ 24V
Smart low-side power switches with high energy capability for 24V automotive and industrial applications
Classic HITFET™ 24V is the established family of low-side switches for automotive and industrial applications. Thanks to their proven technology, the reliable devices are the right solution for applications that require high robustness and energy capability. The family consists of single- and dual-channel switches from 18 mΩ to 550 mΩ in three different packages: TO-252, SOT-223, and DSO-8.
Classic HITFET™ 24V low-side switches from Infineon offer different protection features, such as short circuit and overload protection, protection against voltage surges (or open circuit), overtemperature and electrostatic discharge (ESD) protection. Furthermore, Classic HITFET™ 24V provide fault detection and diagnostic via a feedback loop system and are extremely robust and reliable.
Same as for Infineon’s Classic HITFET™ 12V family, the 24V low-side switches offer either a latch or a restart protection. Whereas for devices with latch protection the microcontroller controls the timing of the restart, the devices with restart protection “restart” in case the temperature drops below a certain limit and the input is still high.
A key benefit of the Classic 24V low-side switches portfolio is their feature and pin-compatible family concept. In addition, Classic HITFET™ 24V offer high robustness and energy capability due to the bigger packages compared to the new HITFET™+ 24V portfolio in PG-TDSO-8 package.
Classic HITFET™ 24V devices are suitable for driving all kind of resistive, capacitive and inductive loads up to 6A. Additionally, the 24V low-side switches are suitable in numerous fast, high frequency PWM applications, like valve switching, motor control and heating. With their extended output voltage protection by clamping at 60V minimum, Classic HITFET™ 24 are designed to be used for trucks, buses, as well as construction & agriculture vehicles (CAV) in harsh environment as well as for industrial applications.
