Description

This PDF data sheet is for the Allegro ULQ2003A High-Voltage High-Current Darlington Array.

Allegro MicroSystems ULQ2003A High-Voltage High-Current Darlington Array

Ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads, the Series ULQ20xxA high-voltage, high-current Darlington arrays feature continuous load current ratings to 500 mA for each of the seven drivers. At an appropriate duty cycle depending on ambient temperature and number of drivers turned ON simultaneously, typical power loads totaling over 230 W (350 mA x 7, 95 V) can be controlled. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. All devices feature open-collector outputs with integral clamp diodes.
The ULQ2003A have series input resistors selected for operation directly with 5 V TTL or CMOS. These devices will handle numerous interface needs – particularly those beyond the capabilities of standard logic buffers.
The ULQ2003A is the standard Darlington arrays. The outputs are capable of sinking 500 mA and will withstand at least 50 V in the OFF state. Outputs may be paralleled for higher load current capability.
These Darlington arrays are furnished in 16-pin dual in-line plastic packages (suffix “A”). All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. The devices are rated for operation over the temperature range of -40 deg C to +85 deg C.
