Overview
The BD18342FV-ME2 is an LED lighting driver IC designed for automotive applications, featuring a 70V high-voltage current controller topology. It supports PWM dimming and includes protection mechanisms such as thermal shutdown and overvoltage mute. The device operates within a supply voltage range of 4.5V to 70V and functions across an industrial temperature range from -40°C to +125°C. Packaged in an HTSSOP-B-20 format, it is AEC-Q100 qualified for automotive reliability.
Feature Summary
- Integrated high-voltage current control suitable for automotive LED lamp arrays
- Supports PWM dimming functionality for brightness adjustment
- Built-in thermal shutdown and overvoltage mute protection circuits
Applications
- Automotive exterior LED lighting systems
- High-voltage LED headlamp modules
- LED tail light assemblies requiring robust current regulation
Procurement Notes
Verify the specific suffix ME2 against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure design compliance with AEC-Q100 standards for automotive deployment. Cross-reference pinout configurations with target PCB layouts prior to procurement to avoid integration errors.
Selection Notes
Select this component when designing LED drivers requiring up to 70V input tolerance. It is appropriate for single-channel constant current applications where PWM dimming is required. Consider its thermal performance and HTSSOP-B-20 footprint constraints during the schematic capture phase.
Part Context
This part belongs to ROHM's automotive-grade LED driver family, specifically engineered for high-reliability vehicle lighting. It complements other buck and buck-boost topologies by offering a dedicated solution for high-voltage direct drive scenarios without external switching elements.
Replacement Considerations
Consult official substitution lists for equivalent ROHM parts with matching voltage ratings and pinouts. Verify functional compatibility if replacing with similar automotive LED controllers from other manufacturers.
