Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the specified range of 8V to 35V.
   • Use appropriate decoupling capacitors (e.g., 0.1μF and 10μF) close to the VDD pin to stabilize the supply.

2. Logic Inputs:

   • Apply logic input voltages (VIN) within the range of 2.5V to 5.5V.
   • Ensure logic signals are clean and free from noise to avoid false triggering.

3. Thermal Management:

   • Place the device on a heatsink or PCB with adequate copper area to manage heat dissipation.
   • Monitor the junction temperature to ensure it does not exceed 150°C.

4. Output Current:

   • Do not exceed the maximum output current of 3.5A per channel to prevent damage.
   • If driving high-current loads, consider using external transistors or FETs.

5. Protection Features:

   • The device includes short-circuit protection (SCP) and over-temperature protection (OTP).
   • In case of a fault, the device will automatically shut down to prevent damage. Once the fault condition is removed, the device will reset and resume operation.

6. Standby Mode:

   • To enter standby mode, set the enable pin to a low logic level.
   • The quiescent current in standby mode is typically 10μA, reducing power consumption when not in use.

7. Signal Timing:

   • Ensure that the propagation delay (tpd) is accounted for in your timing calculations.
   • Use appropriate rise and fall times (tr and tf) to avoid signal distortion and ensure reliable operation.

8. Storage and Handling:

   • Store the device in a dry environment within the temperature range of -65°C to 150°C.
   • Handle the device with care to avoid static discharge, which can damage the internal components.

By following these parameters and instructions, you can ensure reliable and efficient operation of the A4970GLBTR-T.
