Product Overview

The BQ24072RGTT is an USB-friendly Li-ion Battery Charger and power-path management Integrated Circuit targeted at space-limited portable applications. The device operates from either an USB port or an AC adapter and support charge currents up to 1.5A. The input voltage range with input overvoltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the BQ2407 to meet USB-IF inrush current specifications. Additionally, the input dynamic power management (VIN-DPM) prevents the charger from crashing incorrectly configured USB sources. The IC features dynamic power path management (DPPM) that powers the system while simultaneously and independently charging the battery. The DPPM circuit reduces the charge current when the input current limit causes the system output to fall to the DPPM threshold. Thus, supplying the system load at all times while monitoring the charge current separately.
  • Fully compliant USB charger
  • Integrated Dynamic Power Path Management (DPPM) function simultaneously
  • System output tracks battery voltage
  • Programmable pre-charge and fast-charge safety timers
  • Reverse current, short-circuit and thermal protection
  • NTC thermistor input
  • Proprietary start-up sequence limits inrush current
  • Status indication charging/done, power good
  • Green product and no Sb/Br
