BD6046GUL-E2

Power Management - Specialized Overview

The BD6046GUL-E2 is a charging protection IC designed for portable devices, manufactured by ROHM Semiconductor. It safeguards charging ICs from abnormal input voltages up to 28V originating from adapters or USB terminals. The device integrates overvoltage detection, overcurrent detection, undervoltage detection, startup delay, and status detection flag functions. It operates within a supply voltage range of up to 28V and supports an operating temperature range from -40°C to +85°C. The component utilizes a VCSP50L2-13 package and features an open-drain output type without manual reset or watchdog timer capabilities.

Power Management - Specialized Feature Summary

• Integrates multiple protection mechanisms including overvoltage, overcurrent, and undervoltage detection to shield downstream charging circuits from power source anomalies.
• Includes internal startup delay logic to ensure stable initialization sequences during power application.
• Provides status detection flags to indicate specific fault conditions or operational states to the system controller.

Power Management - Specialized Applications

• Protection circuits for portable electronic devices
• Charging interface protection for USB-powered equipment
• Adapter input surge suppression systems

Power Management - Specialized Procurement Notes

Verify the exact ordering part number against the manufacturer's latest datasheet to ensure compatibility with required package variants and suffix codes. Confirm that the VCSP50L2-13 package designation matches your PCB footprint requirements. Check RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region and production batch.

Power Management - Specialized Selection Notes

Select this component when designing protection layers for portable device charging inputs requiring integrated voltage and current monitoring. Ensure the maximum supply voltage rating of 28V aligns with the highest expected transient input levels from adapters or USB sources. Consider the -40°C to +85°C operating range suitability for the intended environmental conditions of the final product assembly.
