Overview
The MAX14671EWL+T is a battery protection integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides comprehensive protection for single-cell lithium-ion or lithium-polymer batteries against overvoltage, undervoltage, overcurrent, and reverse polarity conditions. The device operates within a supply voltage range of 2.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. It is housed in a compact 15-WLP (Wafer Level Package) with dimensions of 1.57mm x 2.14mm, suitable for surface-mount installation.
Feature Summary
- Integrated protection against overvoltage, undervoltage, overcurrent, and battery reverse polarity events
- Compact 15-WLP package design optimized for space-constrained portable applications
- Supports operation with single-cell lithium-ion and lithium-polymer battery chemistries
Applications
- Smartphones and mobile phones
- Portable media players
- Personal digital assistants (PDAs)
- GPS navigation devices
Procurement Notes
Verify the specific suffix 'EWL' corresponds to the 15-WLP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component for designs requiring robust single-cell battery protection in minimal footprint form factors. It is appropriate for consumer electronics where space is limited and reliable power management is critical. Evaluate the trade-off between the WLP package size and assembly requirements compared to larger packages.
Part Context
This part belongs to the Maxim Integrated battery protection family, now part of Analog Devices Inc. It is designed to safeguard rechargeable batteries in portable electronic devices. The WLP packaging distinguishes it from larger BGA or QFN variants within the same functional category.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic cross-references may not match the specific WLP pinout or protection thresholds.
