BD71815AGW-E2

Overview

The BD71815AGW-E2 is a specialized Power Management IC (PMIC) designed for battery-powered devices. It integrates five buck converters and eight LDOs within a UCSP55M4C-80 package. The input voltage range spans from 2.9 V to 5.5 V, with output voltages adjustable between 985 mV and 3.35 V. Operating temperatures extend from -40°C to +85°C. Key features include an embedded coulomb counter for fuel gauging, a real-time clock, and thermistor measurement capabilities.

Feature Summary

Integrates five buck converters and eight LDOs for comprehensive power distribution
Includes embedded coulomb counter for accurate battery fuel gauging
Features single-cell linear lithium-ion battery charger with overvoltage protection
Provides dedicated LDOs for DDR reference voltage and secure non-volatile storage

Applications

E-book readers
Media players
Smart devices

Procurement Notes

Verify the specific suffix E2 against official ROHM documentation to confirm package and compliance details. Confirm RoHS status through manufacturer datasheets. Ensure compatibility with I2C interface requirements for system integration. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this PMIC for applications requiring integrated battery management and multiple regulated outputs in a compact form factor. The device suits systems needing precise fuel gauging via the internal coulomb counter. Consider the UCSP55M4C-80 package size constraints during PCB layout. Verify that the 2.9 V to 5.5 V input range aligns with the primary power source characteristics.

Part Context

This component belongs to the BD71815 series of specialized PMICs from ROHM Semiconductor. It is distinct from other series like BD71805 or BD71847 by its specific combination of five bucks and eight LDOs tailored for portable electronics. The part is often evaluated using the BD71815AGW-EVK-101 development board.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult ROHM technical support for potential alternatives if this component becomes unavailable.
