FDMS2380 Rev. A
Typical Characteristics
Typical Application Circuit
The following schematic of an FDMS2380 used in a basic application is just one of several possible variations for this device.
It shows two external and independent controllers, one for each channel, and two solenoids being controlled by the
FDMS2380. Furthermore, it shows the external local V
Maximum Ratings section. The FDMS2380 ground pins GND1 and GND2 are fully isolated; therefore, they are normally
connected together on the PCB.
When designing the PCB for the FDMS2380 the user needs to provide as low a thermal impedance as is possible for both
the V
be quite large and care should be taken to optimize the thermal impedance of the system to maximize the power handling
capability of the device while minimizing the maximum operating temperature.
