Instructions for Using FAN7392:

1. Supply Voltage (Vcc):

   • The supply voltage should be within the range of 4.5V to 20V.
   • Ensure that the power supply is stable and within the specified range to avoid damage to the device.

2. Gate Drive Current:

   • The high-side gate drive current (IOH) is typically 1.2A when Vcc = 15V and VGS = 10V.
   • The low-side gate drive current (IOL) is typically -1.2A under the same conditions.
   • These currents ensure that the MOSFETs are driven effectively and quickly.

3. Propagation Delay Time:

   • The propagation delay time from high to low (tDHL) and from low to high (tDLH) is typically 15ns to 35ns with Vcc = 15V and a load capacitance (CL) of 1000pF.
   • Ensure that these delays are accounted for in your timing calculations to avoid overlap and potential shoot-through.

4. Pulse Width Distortion (tPWD):

   • The pulse width distortion is typically 3ns, which is the difference in propagation delay between the high-to-low and low-to-high transitions.
   • This parameter is important for maintaining the accuracy of the pulse width in your application.

5. Dead Time (tD):

   • The dead time is the period during which both high-side and low-side drivers are off to prevent shoot-through.
   • The typical dead time is 60ns to 120ns, which helps in protecting the MOSFETs from cross-conduction.

6. Temperature Considerations:

   • The maximum operating junction temperature (TJ(MAX)) is 150°C.
   • The storage temperature range (TSTG) is -40°C to 150°C.
   • Ensure that the device operates within these temperature limits to avoid thermal damage.

7. Layout and PCB Design:

   • Use short and wide traces for the gate drive signals to minimize inductance and ensure fast switching.
   • Place decoupling capacitors close to the power pins to provide stable power and reduce noise.

8. Testing and Debugging:

   • Use an oscilloscope to monitor the gate drive signals and output waveforms to ensure proper operation.
   • Check for any signs of overheating or abnormal behavior during testing.

By following these instructions, you can ensure reliable and efficient operation of the FAN7392 in your design.
