ULN2823A Frequently Asked Questions (FAQ)
-
The maximum current that each output can handle is 500 mA. However, the total current drawn from the device should not exceed 1.5 A.
-
To protect the ULN2823A from back-EMF, a diode (such as 1N4001-1N4007) should be connected in parallel with the inductive load, with the anode connected to the load and the cathode connected to the supply voltage.
-
The minimum input voltage required to turn on the output transistors is around 2.5 V, but it's recommended to use a minimum of 3 V to ensure reliable operation.
-
Yes, the ULN2823A can be used to drive a relay. However, the relay's coil current and voltage should be within the ULN2823A's specifications, and a diode should be connected in parallel with the relay coil to protect the ULN2823A from back-EMF.
-
The power dissipation of the ULN2823A can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
