Component

Li-ion charger3.7 V float voltagelinear chargerSOT-23-6programmable charge current

TP4067-3.7V-SOT236 is a linear charger for one 3.7 V lithium-ion cell, with resistor-programmed charging from 3 mA to 600 mA and a SOT-23-6 package.

Best for

  • Compact single-cell lithium-ion charging
  • Low-to-medium current portable products
  • USB or wall-adapter powered charger circuits

Avoid if

  • The battery requires a 4.2 V or 4.35 V charge voltage
  • High charge current cannot tolerate thermal derating
  • A switching charger is required for improved efficiency

Check before use

  • Confirm 3.7 V battery float-voltage requirement
  • Select RPROG for the intended current
  • Check PCB thermal layout above 400 mA
  • Verify external source voltage remains within 4.35 V to 8.0 V
