Power Supply Connection:
- Connect the input voltage (VIN) to a stable power supply within the operating range of 5.5V to 40V.
- Ensure adequate decoupling capacitors are placed close to the VIN pin to minimize noise and transient effects.
Output Configuration:
- The device can deliver a continuous output current up to 1.5A with peaks up to 3.5A.
- For higher peak currents, ensure the application does not exceed the thermal limits and provides sufficient cooling.
Thermal Considerations:
- Monitor the junction temperature to prevent it from exceeding 160°C, which triggers thermal shutdown.
- Use heat sinks or other cooling methods if necessary.
Enable Pin:
- Apply a voltage greater than 2.7V to the enable pin to activate the device.
- Keep the enable pin below 0.8V to keep the device in a low-power state.
Fault Protection:
- The fault flag responds within approximately 2.8μs when an overcurrent or short circuit is detected.
- Check the fault flag status regularly during operation to diagnose issues promptly.
Quiescent Current:
- At no load and with VIN at 12V, the quiescent current is typically around 20mA.
- This value should be considered in power budget calculations.
Handling and Storage:
- Store the device in anti-static packaging to avoid damage.
- Handle with care to prevent electrostatic discharge (ESD) damage.
