Description
The ULN2803A Module is monolithic high-voltage, high current Darlington transistor arrays.
Features
• ULN2803A Stepper Motor Driver Module
• Recommended Input Voltage: DC 5.0V
• Output breakdown voltage: 50V
• Output current: 500mA
Applications
• Relay Drivers
• Stepper and DC Brushed Motor Drivers
• Lamp Drivers
• Line Drivers
Application Guide
Each consists of eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500 mA. The Darlington pairs may be paralleled for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
