Instructions for Use:

1. Supply Voltages:

   • Ensure that both high-side (V_BH) and low-side (V_BB) supply voltages are within the specified range (10V to 20V).
   • The under-voltage lockout (UVLO) thresholds are 9.5V for the high side and 8.0V for the low side. If the supply voltage falls below these levels, the device will shut down to protect itself.

2. Input Signals:

   • The input high level voltage (V_IH) should be between 2.0V and 15V.
   • The input low level voltage (V_IL) should be between 0.8V and 2.0V.

3. Output Levels:

   • The output high level voltage (V_OH) on the high side is equal to the supply voltage (10V to 20V).
   • The output low level voltage (V_OL) on the low side should not exceed 2.5V, with a typical value of 0.5V.

4. Propagation Delays:

   • The propagation delay times (t_d(HH), t_d(LL), t_d(HL), t_d(LH)) are typically 40ns for same-level transitions and 65ns for opposite-level transitions.

5. Operating Frequency:

   • The maximum operating frequency (f_MAX) is 500kHz. Ensure that the switching frequency does not exceed this limit.

6. Short-Circuit Protection:

   • The device can handle short-circuit currents up to 3.0A on both the high side and low side, with a typical value of 2.0A.

7. Temperature Considerations:

   • The maximum junction temperature (T_J(MAX)) is 150掳C. Ensure proper heat dissipation to prevent overheating.
   • The storage temperature range (T_STG) is from -40掳C to 150掳C. Store the device in a suitable environment to avoid damage.

8. Layout and PCB Design:

   • Use a well-designed PCB layout to minimize parasitic inductances and capacitances, which can affect performance.
   • Place decoupling capacitors close to the power pins to ensure stable operation.

9. Testing and Troubleshooting:

   • Test the device under controlled conditions to verify its performance.
   • Monitor the supply voltages, input signals, and output levels to diagnose any issues.
