CHARGER — Battery charger

nPM1300 Product Specification

The battery charger is suitable for general purpose applications with lithium-ion (Li-ion), lithium-polymer (Li-poly), and lithium iron phosphate (LiFePO4) batteries. The following sections describe how to configure CHARGER to match the battery type.

The main features of the battery charger are the following:
  • Linear charger for Li-ion, Li-poly, and LiFePO4 battery chemistries
  • Bidirectional power FET for dynamic power-path management
  • Automatic trickle, constant current, constant voltage, and end-of-charge/recharge cycle
  • Maintains VBUS current below programmed limit
  • JEITA compliant with a configurable battery charging temperature profile
Charging is configured and enabled through host software. The voltage and charging current are configurable and the device manages the charging cycle after the charging parameters are defined.

VTERM must be set to a lower voltage than the battery overvoltage protection.
