UDQ2981R Parameter Table

UDQ2981R Instructions

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 5.5V.
   • Use a stable power source to avoid voltage fluctuations that could affect performance.

2. Output Configuration:

   • The UDQ2981R can drive up to 150mA per channel, but it is recommended to keep the output current at or below 100mA for optimal performance.
   • Connect the load between the output pin and ground (GND).

3. Input Signal:

   • The input voltage (V_IN) should be within the range of 0V to 5.5V.
   • Ensure the input signal is clean and free from noise to prevent erroneous triggering.

4. Thermal Management:

   • The thermal resistance (θ_JA) is 120°C/W. Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.
   • Consider using a heatsink if the device will be operated near its maximum current or temperature limits.

5. Operating Temperature:

   • The device can operate within a temperature range of -40°C to 85°C.
   • Store the device in a temperature range of -65°C to 150°C.

6. Quiescent Current:

   • The quiescent current (I_Q) is typically 5μA and can go up to 10μA.
   • This low quiescent current makes the UDQ2981R suitable for battery-powered applications.

7. Output Voltage Drop:

   • The output voltage drop (V_OD) is typically 0.3V when driving 100mA.
   • This voltage drop should be considered when designing the circuit to ensure the load receives the required voltage.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Follow proper soldering techniques to avoid overheating during assembly.

By following these parameters and instructions, you can ensure reliable operation of the UDQ2981R in your application.
