Product Overview

The BQ24230RGTT is an USB friendly Li-ion Charger with dynamic power management. It targeted at space-limited portable applications. The device operates from either an USB port or ac adapter and support charge currents between 25 and 500mA. The high-input-voltage range with input overvoltage protection supports low-cost, unregulated adapters. The USB input current limit accuracy and start-up sequence allow the bq2423x to meet USB-IF inrush current specification. Additionally, the input dynamic power management (VIN-DPM) prevents the charger from crashing poorly designed or incorrectly configured USB sources. 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.
  • Programmable precharge 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
