- Integrates comprehensive fault protection for overcurrent, overtemperature, and overvoltage
- Features programmable charge current control via timer settings
Applications
- Single-cell battery charging in portable electronic devices
- Power management systems requiring multi-chemistry support
- Consumer electronics utilizing rechargeable battery packs
Procurement Notes
Verify component status carefully as the SC802AIMLTRT is listed as obsolete or end-of-life in distributor records. Confirm availability through authorized channels or alternative sourcing strategies. Ensure compatibility with existing design specifications before procurement. Check for valid RoHS compliance documentation and verify package integrity upon receipt.
Selection Notes
Select this component for designs requiring a single-chip solution for various battery types. Consider the 16-MLPQ package size for space-constrained layouts. Evaluate the 1.5A current limit against system power requirements. Verify thermal performance under maximum load conditions given the operating temperature range.
Part Context
This part belongs to Semtech's SC802 series of battery chargers. It is distinct from other PMICs like the SC606 LED drivers or SC202 buck regulators. The SC802 focuses specifically on battery management functions rather than general power conversion or lighting control.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Due to the obsolete status, direct replacements may require design modifications. Consult manufacturer documentation for potential last-time buys or recommended alternatives.
