Instructions for A4953ELJTR-T

  1. Power Supply:

    • Ensure the supply voltage (VDD) is within the range of 8.0V to 45.0V.
    • Use appropriate decoupling capacitors (typically 0.1μF and 10μF) close to the power pins to stabilize the supply.
  2. Logic Inputs:

    • The logic input voltage (VIL) should be between 1.2V and 3.3V for a low state.
    • The logic input voltage (VIH) should be between 2.0V and 5.5V for a high state.
    • Ensure all logic inputs are either tied to ground or VDD to prevent floating states.
  3. Current Limiting:

    • Set the bridge current limit (ILIM) using an external resistor according to the datasheet formula.
    • Monitor the current to avoid exceeding the maximum limit of 2.0A.
  4. Thermal Management:

    • The device has a thermal shutdown threshold of 160°C. Ensure adequate heat dissipation to prevent overheating.
    • Use a heatsink if necessary, especially in high-power applications.
  5. Operating and Storage Temperatures:

    • The operating temperature range (TA) is from -40°C to 150°C.
    • The storage temperature range (TSTG) is from -55°C to 150°C.
  6. Handling and Storage:

    • Handle the device with care to avoid static damage.
    • Store the device in a dry environment to prevent moisture damage.
  7. Application Notes:

    • Refer to the datasheet for specific application notes and circuit diagrams.
    • Ensure all connections are secure and free from short circuits.
