Overview
The BD18337EFV-ME2 is a four-channel automotive LED driver IC manufactured by ROHM Semiconductor. It operates within an input voltage range of 5.5 V to 20 V and delivers up to 600 mA total output current, with 150 mA per channel. The device utilizes PWM dimming and features built-in thermal dispersion circuits for single-pin control of multiple outputs. It is housed in an HTSSOP-B16 package and supports AEC-Q100 Grade 1 qualification.
Feature Summary
- Built-in thermal dispersion circuit allowing single-pin control of multiple outputs to reduce component count
- Integrated LED open circuit detection and ground fault protection on output pins
- Supports PWM dimming for precise brightness control in automotive lighting applications
Applications
- Automotive rear lights including brake lamps and tail lamps
- Fog lamps and turn signals
- License plate illumination
- Daylight running lamps (DRL)
Procurement Notes
Verify the specific suffix ME2 against the official datasheet to confirm package type and RoHS compliance status. Confirm functional safety classification as FS supportive if safety analysis is required. Check for obsolescence notices as previous listings indicated NRND status for related variants. Ensure compatibility with existing PCB footprints for HTSSOP-B16 packages.
Selection Notes
Select this component when designing automotive lighting modules requiring thermal management across multiple channels. It is suitable for platforms needing generalized circuit designs for various lamp types. Consider the 150 mA per channel limit and 40 V maximum output voltage when sizing external components. Verify that the single-pin thermal dispersion control meets the system's complexity requirements.
Part Context
This part belongs to the BD18337 series of linear LED drivers designed specifically for automotive use. It shares design principles with the BD18347EFV-M series but offers distinct channel configurations and thermal control features. The series is engineered to support functional safety analysis and platform-based development for vehicle lighting systems.
Replacement Considerations
The BD18347EFV-M is documented as a related variant for different LED segment configurations. Verify pinout and electrical specifications before substitution. No direct public substitute part numbers are confirmed for this specific model.
