Product Overview

The BQ25890HRTWT is an I2C controlled single cell 5A fast charger in 24 pin WQFN package. This charger with MaxCharge technology for high input voltage and adjustable voltage USB on-the-go boost mode. It is highly integrated switch-mode battery charge management and system power path management device for single cell Li-ion and lipolymer battery. The device supports high input voltage fast charging. The low impedance power path optimizes switch mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. The I2C serial interface with charging and system settings makes the device a truly flexible solution. It is used in smart phone, tablet PC and portable internet devices.
  • Support 3.9V to 14V input voltage range, optimize for high voltage input (9V/12V)
  • 93% charge efficiency at 2A, 91% charge efficiency at 3A charge current
  • Low power PFM mode for light load operations, support down to 2.5V battery
  • Selectable 500KHz/1.5MHz boost converter with up to 2.4A output
  • 93% boost efficiency at 5V at 1A output, accurate hicc-up mode overcurrent protection
  • Input current limit (100mA to 3.25A) to support USB2.0, USB3.0 standard and high voltage adapters
  • Input current optimizer (ICO) to maximize input power without overloading adapters
  • Resistance compensation (IRCOMP) from charger output to cell terminal
  • Highest battery discharge efficiency with 11mohm battery discharge MOSFET up to 9A
  • BATFET control to support ship mode, wake up and full system reset
