Description
The AUIRL7732S2 combines the latest Automotive HEXFET® Power MOSFET Silicon technology with the advanced DirectFET® packaging to
achieve low gate charge as well as the lowest on-state resistance in a package that has the footprint which is 38% smaller than an SO-8 and only
0.7mm profile. The DirectFET® package is compatible with existing layout geometries used in power applications, PCB assembly equipment and
vapor phase, infra-red or convection soldering techniques, when application note AN-1035 is followed regarding the manufacturing methods and
processes. The DirectFET® package allows dual sided cooling to maximize thermal transfer in automotive power systems.
This HEXFET® Power MOSFET is designed for applications where efficiency and power density are of value. The advanced DirectFET® packaging
platform coupled with the latest silicon technology allows the AUIRL7732S2 to offer substantial system level savings and performance improvement
specifically in high frequency DC-DC, motor drive and other heavy load applications on ICE, HEV and EV platforms. The AUIRL7732S2 can be utilized
together with the AUIRL7736M2 as a control/sync MOSFET pair in a buck converter topology. This MOSFET utilizes the latest processing techniques
to achieve low on-resistance and low Qg per silicon area . Additional features of this MOSFET are 175°C operating junction temperature and high
repetitive peak current capability. These features combine to make this MOSFET a highly efficient, robust and reliable device for high current
automotive applications.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the specifications is not implied. Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability. The thermal resistance and power dissipation ratings are measured under
board mounted and still air conditions. Ambient temperature (TA) is 25°C, unless otherwise specified.
