UDN2987 - 8-CHANNEL SOURCE DRIVER WITH OVER-CURRENT PROTECTION

General Description

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.

2987 8-CHANNEL SOURCE DRIVER 2987 8-CHANNEL SOURCE DRIVER WITH OVER-CURRENT PROTECTION 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. In these drivers, each channel includes a latch to turn OFF that channel if the maximum channel current is exceeded. All channels are disabled if the thermal shutdown is activated. A common FAULT output is used to indicate either chip thermal shutdown or any overcurrent condition. All outputs are enabled by pulling the common OE/ R input high.
