BD94130MUF-ME2

Overview

The BD94130MUF-ME2 is an LED lighting driver IC featuring 24 constant current channels and 8 switch controllers. It operates within a supply voltage range of 3 V to 5.5 V, delivering up to 80 mA per channel with a total maximum output current of 1920 mA. The device supports PWM dimming with 4096 steps and DC dimming with 64 steps via SPI communication at rates up to 20 MHz. Designed for automotive applications, it functions between -40°C and +125°C in a VQFN-56 package.

Feature Summary

• Integrates 24-channel constant current drivers and 8-line switch controllers for backlight systems
• Enables high-resolution dimming through 4096-step PWM and 64-step DC control
• Facilitates microcontroller integration via standard SPI interface
• Supports external ISET resistor configuration for precise LED current setting

Applications

• Automotive instrument cluster panel backlighting
• In-Vehicle Infotainment (IVI) system displays
• High-density LED matrix arrays requiring individual channel control

Procurement Notes

Verify the specific suffix ME2 against the official ROHM datasheet to confirm package type and RoHS compliance status. Ensure the ordering quantity aligns with the factory packaging quantity of 1000 units if purchasing in bulk. Confirm that the VQFN-56 footprint matches the target PCB design requirements before finalizing procurement.

Selection Notes

Select this component when designing automotive display backlights requiring high channel density and precise current regulation. The integrated switch controllers allow direct driving of external components, reducing bill of materials. Verify that the host microcontroller supports the required SPI data transfer rate and that the thermal management strategy accommodates the operating temperature range up to 125°C.

Part Context

This part belongs to the BD94130 series of LED lighting driver ICs from ROHM Semiconductor. It is specifically engineered for functional safety support in automotive environments. The device complements other power management solutions by providing dedicated high-channel-count LED driving capabilities for complex display architectures.

Replacement Considerations

The BD94130EFV-ME2 serves as a pin-compatible alternative utilizing an HTSSOP-B-54 package instead of the VQFN-56 form factor. Both variants share identical electrical specifications and functionality. Verify package dimensions and thermal dissipation characteristics when substituting.
