Controller IC Chip - ISL6258A ISL6258 F945NX F827SJ F927NP LD TQFN-28 chip for laptop- Integrated portable calculator chip (SKU.1-CHIP0117)
The ISL6258, ISL6258A are a highly integrated Narrow VDC system voltage regulator and battery charger controller. Operating parameters are programmable over the System Management Bus (SMBus).
The ISL6258, ISL6258A are designed for applications where the system power source is either the battery pack or the output of the regulator/charger. This makes the max voltage to the system equal to the max battery voltage instead of the max adapter voltage. The ISL6258, ISL6258A also include a system to control trickle charging deeply discharged batteries while maintaining system voltage at a user defined minimum. High efficiency is achieved with a DC/DC synchronous-rectifier buck converter, equipped with diode emulation for enhanced light load efficiency and AC adapter boosting prevention. The ISL6258, ISL6258A can charge two to four series connected Lithium-ion cells, at up to 8A charge current. The ISL6258 has default settings for 2-cell systems and ISL6258A has default settings for 3-cell systems. Integrated MOSFET drivers and bootstrap diode result in fewer components and smaller implementation area. Low offset current-sense amplifiers provide high accuracy
