The LX27901ID-TR is a high-efficiency 2 Amp Hi-Side LED driver integrated circuit optimized for driving a single LED or LED strings with up to 12 LEDs or 1A of current. It is designed to provide a robust LED current regulation and temperature protection in a wide range of industrial and automotive applications, such as automotive backlighting, dashboard lighting, headlamps, and interior lighting.

This LED driver is specifically designed to reduce the demands on high current linear regulators by providing a high efficiency solution. It utilizes a standard MOSFET element to provide up to 1A (2 Amps for bidirectional operation) of LED current with temperature protection and fault protection. The LX27901ID-TR includes an adjustable PWM control input to regulate LED intensity, making it suitable for applications that require LED dimming.

The LX27901ID-TR is configured with a wide 7V-45V operating range and a low dropout voltage to enable design flexibility. This LED driver is able to start up at any voltage above the 9V minimum and is also capable of operating at full current without an external sense resistor. This driver includes a single cycle soft start circuitry so there is no need to perform a slow startup to prevent overshoot.

The LX27901ID-TR is designed with integrated over-temperature protection (OTP) circuitry to protect LEDs from thermal overload. This driver also includes short circuit protection and reverse voltage protection (RVP) features to ensure that the LEDs are not damaged in the event of an unexpected fault condition. This LED driver is also design with a low-noise circuit to keep noise levels in controlled environment at a minimum.

The LX27901ID-TR can be used in a variety of applications including automotive lighting, LED light strips, stage lighting, sign and display lighting, and general purpose LED light fixtures. This LED driver is suitable for controlling LED strings that require a regulated current over long distances. The device also offers designers a high EMI and ESD performance, making it an ideal solution for automotive lighting and other applications where electrical noise must be kept to a minimum.

The LX27901ID-TR offers a simple solution to LED current regulation and temperature protection in a variety of industrial and automotive applications. Its high efficiency solution and wide operating range means that design flexibility is maximized, making it an excellent choice for any LED current regulation requirement.
