Overview
The L99CL01XP is an obsolete octal high-side LED driver IC designed for automotive exterior and interior lighting applications. It features eight fully protected switches with programmable overcurrent thresholds and RDSON. The device supports a split supply range of 6 V to 24 V and utilizes an SPI communication interface with daisy-chain capability. Key functionalities include individual digital diagnosis, analogue current sense output via an SPI programmable multiplexer, and an integrated synchronous PWM module with phase shift control. Additional features comprise improved EMC behavior through edge shaping, a limp-home function with six independent direct drive pins, integrated fail mode handling, and an ultra-low power mode consuming less than 5 μA at 25°C.

Procurement Notes
The L99CL01XP is officially listed as obsolete by STMicroelectronics. Availability is restricted, and the component may no longer be in active production. Verify end-of-life status and last-time-buy dates directly with authorized distributors or the manufacturer before design implementation. Ensure compliance with AEC-Q100 qualification requirements if applicable to the specific application environment.
Selection Notes
This component is suitable for designs requiring an octal high-side driver with advanced diagnostic and EMC capabilities. Consider the obsolete status when selecting this part; alternative solutions from the same family or newer generations should be evaluated for long-term supply stability. The split supply architecture and SPI interface are critical for system integration. Verify pin compatibility and thermal performance against the target PCB layout constraints.
Part Context
The L99CL01XP belongs to the L99CL series of LED lighting drivers from STMicroelectronics. It is categorized under Driver ICs and specifically targets automotive lighting markets. The device is AEC-Q100 qualified, ensuring reliability for automotive environments. It falls within the broader Power & Energy product line, focusing on smart power distribution and efficient LED control solutions for modern vehicles.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers must identify equivalent components based on functional specifications such as channel count, voltage range, and interface type. Consult STMicroelectronics technical support for potential cross-reference recommendations.
