Instructions for Use:

1. Power Supply Connection:

   • Connect the VDD pin to a power supply within the range of 8V to 52V.
   • Ensure VLOGIC is connected to a supply between 2.7V and 5.5V.

2. Current Limiting:

   • Adjust the ILIM resistor to set the peak phase current limit as required by your application, typically between 1.5A and 3.0A.

3. Thermal Considerations:

   • Monitor the device temperature to ensure it does not exceed 160°C to prevent thermal shutdown.

4. Under Voltage Lockout:

   • Verify that the input voltage remains above 8V to avoid entering under voltage lockout (UVLO).

5. Standby Mode:

   • In standby mode, the device consumes approximately 40μA. Ensure this is accounted for in low-power applications.

6. Temperature Range:

   • Operate the device within a junction temperature range of -40°C to 150°C for reliable performance.
