Overview
The BD8379FV-ME2 is a 12-channel serial-in parallel-out LED driver IC manufactured by ROHM Semiconductor. It operates within an input voltage range of 3 V to 5.5 V and supports a maximum switching frequency of 1.25 MHz. Each channel provides an output current capability of 50 mA, with a total maximum output current of 600 mA. The device features a 3-wire serial interface for control and is housed in a compact SSOP-B-20 package. It is designed for surface mount installation and functions reliably across an operating temperature range from -40°C to +105°C.
Feature Summary
- Integrates 12 independent open-drain outputs controlled via a 3-line serial interface.
- Supports cascade connections for expanded system scalability.
- Features internal power transistors with optimized output slew rates to minimize electromagnetic interference noise.
Applications
- Automotive interior lighting systems
- LCD backlight unit control
- General LED illumination arrays
Procurement Notes
Verify the component status carefully before integration, as this part is classified as NRND (Not Recommended for New Designs). Confirm that existing inventory or last-time buy options align with long-term production requirements. Ensure the SSOP-B-20 package dimensions fit the target PCB layout constraints. Validate compatibility with the 3-wire serial protocol used in the host controller design.
Selection Notes
Select this component when a high-density solution for driving multiple LEDs is required within a small footprint. The 12-channel configuration reduces external component count compared to single-channel drivers. The wide operating temperature range makes it suitable for automotive environments. Consider the NRND status when planning for future product lifecycle management and potential obsolescence risks.
Part Context
This IC belongs to ROHM's series of serial-input parallel-output LED drivers designed for space-saving applications. It utilizes an HTSSOP-B20 package variant in some documentation contexts, offering a compact form factor. The device is AEC-Q100 qualified, indicating its suitability for automotive-grade applications requiring robust performance under varying environmental conditions.
Replacement Considerations
The part number alias BD8379FV-M refers to the same functional device. No direct cross-model substitutes are confirmed in the provided data. Designers should evaluate the NRND status implications for long-term supply continuity.
