Note: On PCB (Test Board: JEDEC 2s2p)DescriptionThe ULN2003APG Series are high−voltage, high−current darlington drivers comprised of seven NPN darlington pairs.All units feature integral clamp diodes for switching inductive loads.Applications include relay, hammer, lamp and display (LED) drivers.The suffix (G) appended to the part number represents a Lead (Pb)-Free product.
The ULN2003APG has six features.(1)output current (single output): 500 mA max.(2)high sustaining voltage output: 50 V min.(3)output clamp diodes.(4)inputs compatible with various types of logic.(5)package Type-APG: DIP-16pin.(6)package Type-AFWG: SOL-16pin.This IC does not include built-in protection circuits for excess current or overvoltage.If this IC is subjected to excess current or overvoltage, it may be destroyed.Hence, the utmost care must be taken when systems which incorporate this IC are designed.Utmost care is necessary in the design of the output line, COMMON and GND line since IC may be destroyed due to short−circuit between outputs, air contamination fault, or fault by improper grounding.
When a motor rotates in the reverse direction, stops or slows down abruptly, a current flow back to the motor's power supply due to the effect of back-EMF. If the current sink capability of the power supply is small, the device's motor power supply and output pins might be exposed to conditions beyond absolute maximum ratings. To avoid this problem, take the effect of back-EMF into consideration in system design.
