Product Overview

The ISL9241 combination buck-boost battery charger is ideal for products with USB-C power delivery functionality. This part supports both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck-Boost (HPBB) charging, and switches between the modes using firmware control. It provides a low-cost, small solution size capable of efficiently processing a full range of power levels. The ISL9241 leverages Renesas' advanced R3™ modulation technology for superior light-load efficiency and ultra-fast transient response to extend battery run-time. The charger's reconfigurable internal registers allow the use of a smaller inductor for HPBB mode to achieve higher efficiencies across multiple power levels. An integrated 8-bit ADC provides digital telemetry to monitor key system parameters on battery and adapter side as well as the system side - including battery voltage, charge/discharge current, adapter input voltage and current, system bus voltage and system temperature. The ISL9241 al
  • Buck-boost NVDC and HPBB charger for 2-, 3-, or 4-cell Li-ion batteries
  • Input voltage range of 3.9V to 23.4V (no dead-zone)
  • System/battery output voltage of 3.9V to 18.304V
  • Bypass mode supports system connection to adapter
  • Adapter current and battery current monitor (AMON/BMON)
  • Supports supplemental power (Intel VMIN active protection)
  • Programmable autonomous charging, and end of charge timer to stop battery charging
  • Integrated 8-bit ADC enables system telemetry: temperature (PCB and junction), adapter current/voltage, battery charge/discharge current, and system bus voltage
  • Compliant with Intel PROCHOT# and PSYS for protection against battery voltage drop, adapter over-current, battery over-current and overheat
  • Allows trickle charging of depleted battery
  • SMBus/I2C allows programming of key parameters to deliver a customized solution
  • Battery ship mode keeps IC in ultra-low power state
