The BORN SEMICONDUCTOR BULN2003A is a versatile 50V, 500mA Darlington transistor array designed for driving higher current loads from low-voltage logic. It features seven NPN Darlington pairs with high-voltage outputs and integrated common-cathode clamp diodes for switching inductive loads. Each Darlington pair includes a 2.7k series base resistor, enabling direct operation with TTL or 5V CMOS devices. Applications include relay drivers, hammer drivers, lamp drivers, display drivers, line drivers, logic buffers, stepper motors, IP cameras, and HVAC valves.

The BULN2003A integrates seven high-voltage, high-current NPN Darlington transistor pairs, each capable of sinking up to 500 mA. These pairs feature common emitters and open collector outputs, along with integrated suppression diodes to protect against inductive load kick-back. A 2.7k series base resistor on each input allows for direct interfacing with TTL or 5V/3.3V CMOS logic. The device is suitable for applications requiring significant current sourcing or sinking capabilities, such as driving relays, solenoids, lamps, and small motors. Outputs can be paralleled for increased current handling.
The BULN2003A is ideal for interfacing low-voltage microcontrollers or logic devices with higher voltage and current peripherals. A common application involves driving inductive loads like motors, solenoids, and relays. Key design considerations include input voltage range, temperature range, output drive current, and power dissipation. The coil current is determined by the coil voltage, coil resistance, and the output low voltage (VCE(SAT)). On-chip power dissipation must be managed to stay within the device's thermal limits, with a recommended junction temperature limit below 125C.
While the part itself does not require a separate power supply, the COM pin is typically tied to the system power supply. Care must be taken to ensure the output voltage does not significantly exceed the COM pin voltage to prevent excessive forward biasing of the flyback diodes, which could lead to overheating or damage.
Use thin traces for inputs due to low current logic signals. Separate input channels to minimize crosstalk. Employ thick traces for outputs to accommodate high currents. The common emitter return trace should be sized to be very wide, capable of handling up to 2.5 A in some applications.
