XT2059 - Programmable voltage and current linear battery management chip

Description

The XT2059 is charging management circuit that can be programmed through an external resistor constant current / constant voltage charging.

The device includes an internal power transistor, does not need external current sense resistor and blocking diode in applications.

Features

  • In the package allows the range of programmable charge current up to 1.2A above.
  • No MOSFET, sense resistor or blocking diode required.
  • Complete linear charger in small package for single cell lithium-ion batteries.
  • Constant-current/constant-voltage operation with thermal regulation to maximize charge rate without risk of overheating.
  • Charging voltage can be adjusted by the FB.
  • Monitor output charge current.
  • Charging status indicator and full status flag.

XT2059 Programmable voltage and current linear battery management chip ■ General Description The XT2059 is charging management circuit that can be programmed through an external resistor constant current / constant voltage charging. The device includes an internal power transistor, does not need external current sense resistor and blocking diode in applications. XT2059 requires minimal external components, and meet the USB bus specification, is very suitable for portable applications in the field. Thermal modulation circuit can control the internal chip temperature in a safe range when the device power dissipation be relatively large or the ambient temperature be higher. The output voltage can be programmed by an external resistor. Charging current is set by an external resistor.
