Introduction

AI Translation

The BQ25883 is a highly integrated 2A boost switch-mode battery charging management and system power path management device, suitable for two-cell (2s) lithium-ion and lithium-polymer batteries. The BQ25883 features I²C control, OTG, and power path functions.

Features

AI Translation
  • Efficient 2A 1.5MHz switch-mode boost charger with 93.4% charging efficiency at 5V adapter, 7.6V battery, 1A charge
  • Optimized for USB input and 2-cell Li-ion batteries
  • Optional low-power PFM mode for light-load operation
  • Single input supporting USB input adapter
  • 3.9V to 6.2V input voltage range with 20V absolute maximum input voltage rating
  • Input current limit (500mA to 3.3A, 100mA accuracy) supporting USB2.0, USB3.0 standard adapters
  • Maximum power tracking via input voltage limit up to 5.5V
  • Integrated USB D+/D- auto-detection for USB SDP, CDP, DCP, and non-standard adapters
  • Power path management and I²C control
  • 17mΩ battery discharge MOSFET for maximum battery discharge efficiency
  • Narrow VDC (NVDC) power path management for instant-on operation without battery or with deeply discharged battery
  • Ideal diode operation in battery charging mode
  • USB On-the-Go (OTG) function with adjustable output voltage range of 4.5V to 5.5V
  • Buck converter with up to 2A output
  • 94% efficiency at 5V, 1A output
  • Precise constant current (CC) regulation and output short-circuit protection
  • Optional low-power PFM mode for light-load operation with silent option
  • Input Current Optimizer (ICO) to maximize input power without overloading the adapter
  • Integrated 16-bit ADC for system monitoring (bus voltage and current, battery voltage, charge current, system voltage, NTC and die temperature)
  • High integration includes all MOSFETs, current sensing, and loop compensation
  • ±0.5% charge voltage regulation
  • ±5% charge current regulation
  • ±7.5% input current regulation
  • Safety: battery temperature detection, thermal regulation, and thermal shutdown in charging and OTG buck modes
