Figure 12. Typical Applications
The loads must be chosen in order to guarantee the device
normal operating condition for junction temperatures from -40
to 150°C. In case of permanent short-circuit conditions, the
duration and number of activation cycles must be limited with
a dedicated MCU fault management, using the fault reporting
through the SPI. When driving DC motor or Solenoid loads
demanding multiple switching, an external recirculation
device must be used to maintain the device in its Safe
Operating Area.
• AN3274, which proposes safe configurations of the
eXtreme Switch devices in case of application faults, and
to protect all circuitry with minimum external components.
• AN2469, which provides guidelines for Printed Circuit
Board (PCB) design and assembly.
Development effort will be required by the end users to
optimize the board design and PCB layout, in order to reach
electromagnetic compatibility standards (emission and
immunity).
