BD81010MUV-E2

Overview

The BD81010MUV-E2 is a specialized Power Management IC designed for Gamma TFT-LCD applications. It integrates a DAC and operates within an input voltage range of 2.1 V to 3.6 V, with a maximum input voltage tolerance of 18 V. The device provides an output current of 50 mA and consumes 8.6 mA during operation. It supports a power dissipation of 4.56 W and functions reliably between -40°C and +85°C. Packaged in a VQFN-32 format, it serves as a gamma voltage generator for display panels.

Feature Summary

• Integrates a Digital-to-Analog Converter (DAC) specifically for generating gamma voltages in TFT-LCD systems.
• Supports wide input voltage tolerance up to 18 V while operating on low core supply voltages.
• Includes built-in protection circuits to ensure stable operation under varying thermal conditions.

Applications

• Gamma voltage generation for TFT-LCD panels
• Professional power management in display driver circuits

Procurement Notes

Verify the component status before procurement, as this part is marked as Not Recommended for New Designs (NRND). Confirm that existing inventory meets project requirements since new design adoption is discouraged. Ensure compatibility with VQFN-32 mounting standards and validate that the 50 mA output capability aligns with specific panel drive needs. Check for RoHS compliance details if environmental regulations apply to the final assembly.

Selection Notes

Select this component when designing for legacy or existing TFT-LCD panel architectures requiring dedicated gamma correction. The wide input voltage tolerance allows flexibility in system power rail design. Consider the NRND status carefully; alternative newer models from the manufacturer should be evaluated for long-term supply chain stability. Verify that the thermal performance at 4.56 W dissipation fits the enclosure constraints.

Part Context

This component belongs to ROHM Semiconductor's professional PMIC line focused on display technologies. It addresses the specific need for precise gamma voltage generation in liquid crystal displays. The VQFN-32 package offers a compact footprint suitable for space-constrained mobile and consumer electronics devices requiring high-density integration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, consult the manufacturer for recommended upgrades or equivalent series components suitable for new designs.
