Overview
The BH6942KN-E2 is an LED lighting driver IC from ROHM Semiconductor, specifically designed as a backlight LED driver with an integrated charge pump. It operates within a supply voltage range of 2.8 V to 4.5 V and supports surface-mount installation in SMD/SMT configurations. The component functions within a temperature range of -30°C to +80°C and has a maximum power dissipation of 530 mW. This device belongs to the BH6942KN series and is classified under LED Lighting Drivers.
Feature Summary
- Integrated charge pump functionality for backlight LED driving
- Supports low-voltage operation between 2.8 V and 4.5 V
- Designed for surface-mount technology (SMD/SMT) applications
Applications
- Backlight LED drivers for display systems
Procurement Notes
Verify current availability status as the BH6942KN-E2 is listed as End-of-Life (EOL). Manufacturers have indicated that this product will be discontinued and is no longer recommended for new designs. Confirm lead times and substitute options through authorized distributors before finalizing procurement plans.
Selection Notes
Select this component only if legacy compatibility with the BH6942KN series is required. Ensure the design accommodates the specific 2.8 V to 4.5 V input voltage window and the -30°C to +80°C operating temperature range. Consider alternative drivers if new design rules prohibit EOL components.
Part Context
The BH6942KN-E2 is part of ROHM's portfolio of LED lighting driver ICs. It serves as a specialized solution for managing backlight illumination in electronic displays. The 'E2' suffix typically denotes environmental compliance or specific manufacturing revisions within the ROHM naming convention, though functional differences are not explicitly detailed in general summaries.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the End-of-Life status, direct replacements must be identified through official ROHM discontinuation notices or engineering evaluation of compatible backlight driver ICs.
