Overview
The BD18327EFV-ME2 is a single-channel LED driver designed for two-wheeler vehicle turn indicators, featuring a 50V withstand voltage and 1.5A total output current capability. It operates within an input voltage range of 6V to 18V and supports PWM dimming. The device integrates a built-in CR timer for flasher control and meets AEC-Q100 Grade 1 standards with an operating temperature range of -40°C to 125°C. Packaged in HTSSOP-B20, it provides functional safety support.
Feature Summary
- Built-in CR timer controls LED flashing frequency without external components
- Detects LED open circuits by doubling the output flash frequency
- Reduces PWM duty cycle under high input voltage to manage IC heat
- Includes short circuit protection and overvoltage protection mechanisms
Applications
- Two-wheeler vehicle turn indicator lighting systems
- Automotive LED load driving applications requiring high reliability
- Flasher signal generation for vehicle exterior lighting
Procurement Notes
Verify the specific suffix ME2 against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component meets AEC-Q100 Grade 1 requirements for your automotive application. Confirm RoHS compliance status directly from the latest production documentation before integration.
Selection Notes
Select this component for applications requiring a single-channel driver with integrated timing functions. It is suitable where high input voltage handling up to 50V is necessary. Consider its thermal management features when designing for high ambient temperatures or sustained operation in enclosed spaces.
Part Context
This part belongs to ROHM's automotive-grade LED driver series, specifically tailored for motorcycle lighting. It complements other drivers like the BD18354MUF and BD18347AEFV in complete lighting solutions. The series emphasizes functional safety support and robust protection features for critical vehicle signaling.
Replacement Considerations
Check for direct substitutes within the BD1832x series. Verify pin compatibility and electrical parameters if considering alternatives. No public confirmed substitute part numbers are listed in the provided data.
