Overview
The BD8668GW-E2 is a battery management IC designed for lithium-ion batteries, featuring an 8.4V charge output and current limiting capabilities. It operates on a 5V supply voltage with a quiescent current of 60 uA. The device supports a power dissipation of 1W and functions within a temperature range of -30°C to +85°C. Packaged in a USCP75M2-25 SMD/SMT format, it is classified under PMIC - Power Management ICs.
Feature Summary
- Integrated current limiting functionality for precise charge control
- Supports lithium-ion battery charging applications
- Operates with low quiescent current consumption
Applications
- Lithium-ion battery charging systems
- Portable electronic devices requiring compact power management
- Battery management circuits with current limit requirements
Procurement Notes
Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm package compatibility with the USCP75M2-25 footprint. Ensure design reviews account for potential obsolescence risks associated with discontinued or end-of-life product lines during the sourcing phase.
Selection Notes
Select this component only if the specific 8.4V output and 25-pin USCP75M2-25 package align with existing board layouts. Consider the NRND status carefully against long-term production requirements. Evaluate alternative ROHM battery chargers if future scalability or availability is a primary constraint for the project lifecycle.
Part Context
This part belongs to the ROHM Semiconductor battery management portfolio, specifically targeting lithium-ion charge management. It falls under the broader category of PMICs. The 'E2' suffix typically denotes environmental compliance variations within the series, while the base model BD8668GW indicates the core functional architecture.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, direct replacements should be evaluated based on pin compatibility and electrical specifications rather than official cross-reference lists.
