FAN54042 - Li-Ion Switching Charger

Download the FAN54042 datasheet PDF. This datasheet also covers the FAN54040 variant, as both devices belong to the same li-ion switching charger family and are provided as variant models within a single manufacturer datasheet.

Description

The FAN5404X family includes I2C controlled 1.55 A USBcompliant switch-mode chargers with power path operation and USB OTG boost operation.

Integrated with the charger, the IC supports production test mode, which provides 4.2 V at up to 2.3 A to the system.

Features

  • Fully Integrated, High-Efficiency Charger for Single-Cell Li-Ion and Li-Polymer Battery Packs.
  • Power Path Circuit Ensures Fast System Startup with a Dead Battery when VBUS is Connected.
  • 1.55 A Maximum Charge Current.
  • Float Voltage Accuracy: - 0.5% at 25°C - 1% from 0 to 125°C.
  • 5% Input and Charge Current Regulation Accuracy.
  • Temperature-Sense Input Prevents Auto-Charging for JEITA Compliance.
  • Thermal Regulation and Shutdown.
  • 4.2 V at 2.3 A Production T.
