Product Summary

The ULS2803 is a high-voltage, high-current Darlington array. Featuring continuous load current ratings to 500mA for each of the drivers, the ULS2803 is ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads. Typical power loads totaling over 260 W (350mA x 8, 95 V) can be controlled at an appropriate duty cycle depending on ambient temperature and number of drivers turned on simultaneously. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. The ULS2803 features open-collector outputs with integral clamp diodes.
