TMI4054 - 800mA Li-ion Linear Charger

General Description

The TMI4054 is a complete constant-current and constant-voltage linear charger for single cell Li-ion battery application.

The default battery charge voltage is fixed at 4.2V, and the charging current can be programmed by external resistor on PROG pin.

Key Features

  • Programmable Charge Current Up to 1A.
  • No MOSFET, Sense Resistor or Blocking Diode Required.
  • Charge Single Cell Li-Ion Battery Directly from USB Port.
  • Trickle Current, Constant Current and Constant Voltage Operation with Thermal Regulation to Maximize Charge Rate without Overheating.
