Product Overview

The BQ24072TRGTT is an integrated Li-ion Linear Charger and System Power Path Management Device targeted at space-limited portable applications. The device operates from either an USB port or AC adapter and support charge currents up to 1.5A. The input voltage range with input over-voltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the BQ2407XT to meet USB-IF inrush current specification. It 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. This feature reduces the number of charge and discharge cycles on the battery, allows for proper charge termination and enables the system to run with a defective or absent battery pack.
  • Fully compliant USB charger
  • 28V Input rating with over-voltage protection
  • Battery disconnect function with SYSOFF input
  • Reverse current, short-circuit and thermal protection
  • Flexible voltage based NTC thermistor input
  • Proprietary start up sequence limits inrush current
  • Status indication - Charging/done, power good
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
