bq25895 5 A Fast Charger MaxCharge™ Technology

Texas Instruments offers its single cell 5 A fast charger MaxCharge technology for high input voltage and 3.1 A boost

Image of Texas Instruments' bq25895 5 A Fast Charger MaxCharge™ TechnologyTexas Instruments' bq25895 is a highly integrated 5 A switch-mode battery-charge and system-power-path management device for single cell Li-ion and Li-polymer 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.

Features
  • High-efficiency 5 A, 1.5 MHz switch mode buck charge
    • 93% charge efficiency at 2 A and 91% charge efficiency at 3 A charge current
    • Optimize for high voltage input (9 V / 12 V)
    • Low power PFM mode for light load operations
  • Boost mode operation with adjustable output from 4.5 V to 5.5 V
    • Selectable 500 KHz / 1.5 MHz boost converter with up to 3.1 A output
    • 93% boost efficiency at 5 V at 1 A output
  • Integrated control to switch between charge and boost mode
  • Single input to support USB input and adjustable high voltage adapters
    • Support 3.9 V to 14 V input voltage range
    • Input current limit (100 mA to 3.25 A with 50 mA resolution) to support USB2.0, USB3.0 standard, and high voltage adapters
    • Maximum power tracking by input voltage limit up-to 14 V for wide range of adapters
    • Auto detect USB SDP, CDP, DCP, and non-standard adapters
