- Description Providing overcurrent protection for each of its eight sourcing outputs, the UDN2987LW-6 driver is used as an interface between standard low-level logic and relays, motors, solenoids, LEDs, and incandescent lamps. This device includes thermal shutdown and output transient protection/clamp diodes for use with sustaining voltages to 35 V. In this driver, 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. When OE/R is low, all outputs are inhibited and the eight latches are reset. The OE/R function can be especially important during power-up, in preventing floating inputs from turning on the outputs. Under normal operating conditions, each of eight outputs will source in excess of 100 mA continuously at an ambient temperature of 25°C and a supply of 35 V. The overcurrent fault circuit will protect the device from short-circuits to ground with supply voltages of up to 30 V.
