TP4057X-42-SOT236 is a compact linear charger for one 4.2 V Li-ion cell, with programmable charging up to 500 mA and USB-compatible input operation.

Best for

  • Compact single-cell Li-ion chargers
  • USB-powered portable products
  • Low-cost charging cradles

Avoid if

  • Multi-cell battery packs
  • Battery chemistries requiring a float voltage other than 4.2 V
  • Applications requiring high-power switching-charge efficiency

Check before use

  • Set RPROG for the required charge current
  • Confirm PCB thermal performance at 400 mA to 500 mA
  • Keep VCC and BAT bypass capacitors close to the IC
  • Verify input supply remains within the specified operating range
