The SN75437ANEE4 is a high-current peripheral driver from Texas Instruments, designed to interface between low-power logic and high-power loads. It features an open-collector output capable of sinking up to 500mA, making it ideal for driving relays, solenoids, and lamps. It operates from a 4.75V to 5.25V supply and is TTL-compatible. Housed in a 16-DIP package, this driver simplifies the design of industrial and automotive control circuits by integrating high-current switching into a single IC.

  • High Sink Current (500mA): Directly drives relays, solenoids, and lamps without external transistors.
  • Open-Collector Output: Simplifies load switching and allows for various supply voltages on the load side.
  • TTL-Compatible Inputs: Easy to interface with microcontrollers and standard logic.
  • Through-Hole DIP Package: Ideal for prototyping and applications requiring robust mechanical mounting.

Relay and Solenoid Driving

Its 500mA sink capability allows it to directly drive relays and solenoids in industrial control systems, eliminating the need for external power transistors.

LED Display and Lamp Driving

Drive high-current LED displays or incandescent lamps in indicator panels, with the open-collector output simplifying current sinking.

Motor Control (Small DC Motors)

Control small DC motors in appliances or toys by switching the ground side of the motor, using the driver's high current capacity.

Stepper Motor Windings

Drive the windings of small stepper motors, providing the necessary current pulses for precise positioning.

Automotive Load Switching

In automotive systems, it can switch loads like headlights or wiper motors, though external flyback diodes are recommended.

Industrial Valve Control

Actuate pneumatic or hydraulic valves in factory automation, where high current and robust switching are required.
