The DS1874T+ is a precision laser driver IC specially designed to provide secure and reliable laser diode current control. It is well-suited for applications requiring high current accuracy, low-noise and low-ripple current drive, and increased safety and reliability. This device can be used in many different electrical applications including high-speed optical communication systems and sensing applications.
The DS1874T+ features a wide operating temperature range, from -40°C to +85°C, making it suitable for use in a variety of environments. Its wide voltage range makes it an ideal choice for a variety of applications, from medical to industrial. Its output current is adjustable from 0 mA to 10 mA, making it suitable for a wide variety of laser diode applications, from their active region to their maximum power.
The DS1874T+ is designed to allow for accurate and secure control of laser diode currents. This is achieved through an ultra-precise, low-noise regulator that utilizes a current-control loop, whose output is adjustable from 0 mA to 10 mA, with a current limit accuracy of ±0.25%. This feature also enables the device to have a fast transient response time, with no current-honking (<1µs). A dedicated current monitor output is also provided, enabling a designer to read the current value back to ensure the right current level is achieved.
The primary benefit of the DS1874T+ is its safe and stable operation. This is achieved through its laser-trimmed bandwidth, digital-clamp circuitry, short-circuit protection, and brown-out protection. The integrated short-circuit protection, digital-clamp circuitry, and laser-trimmed bandwidth ensures that the laser diode current will not exceed the predetermined safe limit. This eliminates the need for error-prone manual trim settings and simplifies design with quick, fail-safe protection against over-current situations.
The DS1874T+ is ideally suited for use as a laser diode driver in a variety of high-speed optical communication systems and sensing applications. This device has been designed to provide robust high-current performance and maximum reliability. Its wide voltage range, wide input range, and its built-in current limit protection make it an ideal choice for a variety of high-performance application fields.
