HITFET™ +24V
The HITFET™ + 24V family is the new generation of smart low-side switches for automotive and industrial applications based on a SMART6 HV technology.
The family offers single channel devices with a significant shrink compared to the existing Classic HITFET™ 24V portfolio (up to 50 percent shrink).
The whole portfolio is qualified and optimized for 24 V automotive and industrial applications.
The overtemperature protection prevents the device from overheating due to overload/or bad cooling conditions. All HITFET™ + 24V devices have latch thermal shut-down function. To restart the device an external toggling INPUT must be performed by the µC, providing that the measured temperature has dropped below the thermal hysteresis. The overvoltage protection can be activated during load dump or inductive turn off. The power MOSFET limits the drain-source voltage, if it rises above the VOUT(CLAMP).
Furthermore HITFET™ + 24V products offer improved and additional features, such as driving applications with high switching speed requirements (up to 20kHz depending on DC), dynamic temperature protection which improved the short circuit robustness of the devices (10x better than the Classic HITFET™ 12V) and dedicated STATUS signal for offering Digital diagnosis
A dedicated SRP pin offers the designer to easily balance EMI / switch losses based on his application requirement, with a simple external resistor connected to GND, and a dedicated VDD pin provides the IC supply getting the device RDS(ON) independent from the Input voltage.
In terms of protection features, HITFET™ + 24V is offering: enhanced short circuit operation, new benchmark current limitation concept, overvoltage protection and ESD protection.
The keys for the success of HITFET™ + 24V in the automotive market are the smaller package size for area savings, the best-in-class short circuit robustness, the easily balanced EMC behavior vs. power dissipation in high-speed PWM applications and the simple, fast and reliable diagnostic.
The family scalability combined with the protection and diagnostic features makes the HITFET™ + 24V family suitable for automotive and industrial applications, such as resistive, inductive and capacitive loads limited by the maximal clamping energy and current capabilities of the device.
The fast switching capability makes the HITFET™ + family perfectly suitable for vales and applications with fast PWM (up to 20 kHz).
