Instructions for Use

1. Supply Voltage (V_DD):

   • Ensure the supply voltage is within the range of 10V to 20V.
   • The under-voltage lockout (UVLO) will activate if V_DD drops below 9.5V.

2. High-Side Driver Supply (V_HB):

   • The high-side driver can operate with a supply voltage ranging from 10V to 600V.
   • Ensure proper decoupling capacitors are used to stabilize the high-side supply.

3. Low-Side Driver Supply (V_LB):

   • The low-side driver operates with a supply voltage between 10V and 20V.
   • This should be the same as V_DD.

4. Input Levels:

   • The input high level (V_IH) should be at least 2.0V.
   • The input low level (V_IL) should not exceed 0.8V.

5. Output Levels:

   • The output high level (V_OH) will be between 8.5V and 17V when V_DD is between 10V and 20V.
   • The output low level (V_OL) will be less than or equal to 1.5V.

6. Timing Parameters:

   • The propagation delay time (t_d) is typically 50ns.
   • The rise time (t_r) and fall time (t_f) are both typically 25ns.

7. Current Ratings:

   • The quiescent current (I_Q) is typically 1.5mA.
   • The short-circuit current (I_SC) is limited to 10A for 100ms to prevent damage.

8. Operating Temperature:

   • The device can operate in ambient temperatures ranging from -40°C to 125°C.

9. Protection Features:

   • The device includes over-voltage lockout (OVLO) which activates at 23V.
   • Ensure that the device is not exposed to voltages exceeding its maximum ratings to avoid damage.

10. Layout Considerations:

    • Use short, wide traces for power and ground connections to minimize inductance.
    • Place decoupling capacitors close to the IC to reduce noise and improve stability.

11. Handling:

    • The IR21084S is sensitive to electrostatic discharge (ESD). Use appropriate ESD protection measures during handling and installation.
