Instructions for Using FAN7314

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 20V.
   • Use a stable power source to avoid fluctuations that could affect performance.

2. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 150°C.
   • Store the device in an environment between -65°C and 150°C.

3. Gate Drive Current:

   • For high-side gate drive, ensure the current does not exceed 4A when V_GS is 15V.
   • For low-side gate drive, ensure the current does not exceed -1A when V_GS is -6V.

4. Propagation Delay and Pulse Width Distortion:

   • The propagation delay time (t_d) should be around 80ns under typical conditions.
   • The pulse width distortion (t_pd) should be around 10ns under typical conditions.

5. Output and Input Current:

   • The maximum output current (I_OUT) is 4A at V_CC = 15V.
   • The maximum input current (I_IN) is 100μA at V_CC = 15V.

6. PCB Layout:

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

7. Protection:

   • Implement appropriate overvoltage and overcurrent protection circuits to safeguard the device.
   • Use heat sinks if operating at high temperatures or under high load conditions.

8. Testing:

   • Perform initial testing with a simple load to verify correct operation.
   • Gradually increase the complexity of the circuit while monitoring performance parameters.
