Overview
The BD18341FV-M is an automotive-grade constant current controller designed for LED lighting applications. It supports a wide input voltage range from 4.5 V to 19 V and delivers up to 400 mA output current. The device utilizes Boost and Buck topologies with an operating frequency between 100 Hz and 5 kHz. It features PWM dimming, adjustable output voltage, and operates within a temperature range of -40°C to +125°C. Packaged in SSOP-B-16, it meets AEC-Q100 standards.
Feature Summary
- Supports driving multiple external PNP transistors for high-current LED loads
- Integrates standby functionality to reduce system power consumption
- Includes comprehensive protection mechanisms such as short circuit and over-voltage mute
- Provides LED open detection and abnormal output status monitoring
Applications
- Automotive exterior LED lighting systems
- High-reliability automotive interior illumination
- LED lamp groups requiring low standby power
- Constant current driver circuits for vehicle safety lights
Procurement Notes
Verify the specific suffix (e.g., ME2) against official ROHM documentation to ensure correct packaging and tape specifications. Confirm AEC-Q100 qualification status and functional safety support requirements prior to integration. Cross-reference pinout details with the latest datasheet to avoid interface mismatches during PCB layout.
Selection Notes
Select this component for designs requiring high voltage tolerance and multi-transistor drive capability. Ensure the application environment stays within the specified -40°C to +125°C operational range. Verify that the required LED current does not exceed the 400 mA limit per channel. Consider the SSOP-B-16 package size for space-constrained automotive layouts.
Part Context
This part belongs to ROHM's automotive LED driver family, specifically engineered for robust performance in vehicle environments. It complements other BD183xx series controllers by offering enhanced fault detection and multi-device control capabilities. The design focuses on reducing external component count while maintaining high reliability standards for critical lighting functions.
Replacement Considerations
BD18341FV-ME2 is a confirmed variant within the same product line. Verify if the ME2 suffix indicates specific tape-and-reel packaging differences or minor parameter adjustments compared to the base model before substitution.
