As with all power integrated circuits, the UDN2987A and UDN2987LW have a maximum allowable output current rating.
The 500 mA rating does not imply that operation at that value is permitted or even obtainable.
The channel output current trip point is specified as -370 mA, minimum; therefore, attempte
2987 Providing over-current protection for each of its eight sourcing outputs, the UDN2987A and UDN2987LW drivers are used as an interface between standard low-level logic and relays, motors, solenoids, LEDs, and incandescent lamps.
The device includes thermal shutdown and output transient protection/clamp diodes for use with sustaining voltages to 35 V.
