Application Scenarios & Design Considerations

Li-ion/Li Polymer Battery Charger

Alternative Part Number

  • BQ24070RHLR --: Single-cell Li-ion linear charger in a QFN package with similar charge-management functionality and programmable current, a common drop-in style alternative to the ISL6292 family.
  • LTC4054ES5-4.2 --: Compact standalone single-cell Li-ion linear charger with constant-current/constant-voltage profile, widely used as a functional substitute for small ISL6292 chargers.
  • MCP73831T-2ACI/OT --: Low-cost single-cell Li-ion/Li-Po linear charge controller with similar CC/CV charging behavior, suitable for space-constrained designs replacing the ISL6292-1CR4Z.
