Overview
The BD83816EFV-ME2 is a serial-in parallel-out LED driver IC manufactured by ROHM Semiconductor. It features 16 open-drain outputs controlled via a 3-line serial interface, supporting PWM dimming. The device operates within an input voltage range of 3 V to 5.5 V and delivers up to 50 mA per channel with a total output current capacity of 800 mA. It withstands voltages up to 35 V and functions reliably between -40°C and +125°C. Packaged in HTSSOP-B24, it meets AEC-Q100 Grade 1 standards for automotive applications.
Feature Summary
- Supports 16-channel open-drain output control via 3-line serial interface
- Integrated PWM dimming capability for precise brightness regulation
- Qualified for automotive environments under AEC-Q100 Grade 1 standards
- Designed for space-saving implementation using compact HTSSOP-B24 packaging
Applications
- Automotive LCD backlight systems
- High-brightness LED lighting arrays
- Interior vehicle illumination control
- Exterior automotive lighting modules
Procurement Notes
Verify the specific suffix ME2 against official ROHM documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with 3-wire serial protocols and check thermal requirements for the HTSSOP-B24 package. Confirm AEC-Q100 Grade 1 qualification status matches project safety integrity levels before finalizing procurement orders.
Selection Notes
Select this component when designing automotive displays requiring high channel density and robust serial control. The 35 V rating suits medium-sized panels, while the wide temperature range ensures reliability in harsh engine compartments or exterior mounts. Consider the 50 mA per-channel limit for LED string configurations and verify power dissipation capabilities within the specified operating envelope.
Part Context
This part belongs to the BD83816 series of serial LED drivers from ROHM. It shares architectural similarities with other automotive-grade drivers like the BD83812EFV-M but offers higher channel count. The series targets modern vehicle infotainment and ADAS display backlights where space efficiency and functional safety support are critical design constraints.
Replacement Considerations
The BD83816EFV-M serves as a direct equivalent without the ME2 suffix variant. Verify pinout compatibility and electrical parameters against the latest datasheets before substitution.
