Instructions for Use:

1. Supply Voltage (V_DD):

   • Ensure the supply voltage is within the specified range of 10V to 20V to avoid damage or improper operation.

2. Under Voltage Lockout (UVLO):

   • The device will not operate if the supply voltage drops below 8.5V. This feature protects the device from operating under insufficient voltage conditions.

3. High-Side Floating Supply Voltage (V_BOOT):

   • The high-side driver can operate with a floating supply voltage up to 600V. Ensure that the bootstrap capacitor is properly charged to maintain this voltage.

4. Driver Output Current:

   • Both high-side and low-side drivers can provide a peak output current of 2A. This is sufficient for driving most MOSFETs and IGBTs.

5. Propagation Delay:

   • The typical propagation delay from input to output is 75ns. This should be considered when designing timing circuits.

6. Matched Propagation Delay:

   • The difference in propagation delay between the high-side and low-side drivers is typically 15ns. This helps in minimizing dead time and cross-conduction issues.

7. Operating Temperature Range:

   • The device is designed to operate within an ambient temperature range of -40°C to 125°C. Ensure adequate cooling if operating near the upper limit.

8. Storage Temperature Range:

   • Store the device in an environment where the temperature does not exceed -65°C to 150°C to prevent damage.

9. Junction Temperature:

   • The maximum junction temperature is 150°C. Ensure proper heat dissipation to keep the junction temperature within this limit.

10. Handling Precautions:

    • Handle the device with care to avoid electrostatic discharge (ESD) damage. Use ESD protection equipment and follow standard handling procedures.
