Li-ion chargerlinear charger4.2 V1 AESOP8

TP4066-4.2V-ESOP8 is an 8-pin linear charger for one Li-ion cell, with 4.2 V regulation and programmable charging current up to 1 A.

Best for

  • Single-cell Li-ion charging
  • Compact USB or adapter-powered equipment
  • Applications requiring simple charge-status outputs

Avoid if

  • A switching charger is required for high efficiency
  • The battery pack requires multi-cell charging

Check before use

  • Confirm the required 4.2 V battery termination voltage
  • Confirm PCB copper area and thermal performance at the target charge current
  • Confirm the battery NTC network or disable TEMP only when appropriate
