LED Driver IC Procurement Notes

Verify the specific suffix V+ indicates lead-free and RoHS compliance status as per the manufacturer's current documentation. Confirm the package type matches the required 20-TSSOP footprint with the specified exposed pad dimensions for proper PCB layout and thermal management. Ensure the operating temperature range meets the environmental requirements of the target application.

LED Driver IC Selection Notes

Select this component when a single-channel solution is required for high-voltage IR LED strings in automotive DMS applications. Consider the 2.2 MHz switching frequency for smaller external passive components compared to lower-frequency alternatives. Evaluate the 5V to 48V input range compatibility with the vehicle's power supply system before finalizing the design.

LED Driver IC Part Context

This part belongs to the MAX25613 series of automotive-grade LED drivers from Analog Devices/Maxim Integrated. It is distinct from multi-channel variants like the MAX25560 or other single-channel models such as the MAX25603A. The series focuses on providing efficient, high-voltage solutions specifically tailored for safety-critical automotive sensing and monitoring systems.
