Qualified for Automotive Applications

current Darlington transistor arrays. Each consists of

• ESD Protection Exceeds 200 V Using Machine seven npn Darlington pairs that feature high-voltage

Model (C = 200 pF, R = 0) outputs with common-cathode clamp diodes for

• 500-mA-Rated Collector Current (Single Output) switching inductive loads. The collector-current rating

• High-Voltage Outputs: 50 V of a single Darlington pair is 500 mA. The Darlington

pairs can be paralleled for higher current capability.

• Output Clamp Diodes

The ULQ2003A-Q1 has a 2.7-kΩ series base resistor • Inputs Compatible With Various Types of Logic

for each Darlington pair, for operation directly with
