April 22, 2016 Narrow VDC (NVDC) Battery Charger with SMBus Interface Features The ISL88750 is a highly versatile Narrow VDC (NVDC) battery
charger, supporting 2-, 3-or 4-cell batteries. It allows the
battery to work with the adapter together to supply the system
load when it exceeds the adapter capability, referred to as
system Turbo mode. ISL88750 quickly turns on BGATE to
enable the battery to help the adapter provide the system
power in Turbo mode. Adapter current monitor and battery discharging current
monitor Uses NFET for all the switches
-Supports removal of battery during Battery Learn mode
-Actively controlled inrush current to prevent FET damage The ISL88750 uses N-channel MOSFETs (NFETs) for all the
switches to achieve the best performance and lowest BOM
cost. The internal charge pump is capable of turning on all the
NFETs fast or slow depending on the circumstance or the need.
The ability to quickly turn on NFETs prevents system bus
voltage drop when the battery is suddenly removed in Turbo
mode or in Battery Learn mode. SMBus programmable settings and high accuracy Comprehensive protection features include
-Hardware-based adapter current and battery current
limits
-Supports sudden removal of battery in system Turbo
mode The ISL88750 features hardware based adapter current limit …
