Classic HITFET™ 24V | Automotive Low-Side Switch
Over the past years, Infineon’s Classic HITFET™ 24V have established themselves as power protected MOSFETs of choice for low side applications. The automotive qualified family consists of single and dual channel low-side switches (from 18 mΩ to 550 mΩ) in PG-TO252, PG-SOT223 and PG-DSO-8 packages.
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.
A Classic HITFET™ 24V is an automotive qualified low-side switch. The scalable family offers RDS(ON) from 18 mΩ to 550 mΩ and comes in three different packages (PG-TO252, PG-SOT223 and PG-DSO-8). Their technology is proven and established in the market for more than 25 years.
Classic HITFET™ 24V are the ideal fit for 24V automotive and industrial applications, as well as for trucks, buses and construction & agriculture vehicles (CAV) in harsh environment. The 24V low-side switches are capable to drive all kinds of inductive, capacitive and resistive loads up to 6A.
The Classic HITFET™ 24V family offers different protection and diagnostic features, such as short circuit, overload, overtemperature, overvoltage and electrostatic discharge (ESD) protection. The 24V low-side switches are pin-compatible within the Classic HITFET™ 24V family and available as latch and restart devices.
