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.
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.
The ISL88750 features hardware based adapter current limit and battery-current limit in addition to SMBus programmable limits.
The ISL88750 provides a high accuracy adapter current monitor and battery discharging current monitor outputs. To provide maximum flexibility for working with high power and low power systems, it provides several configurable current-sense resistor value options to achieve the best trade-off of current sensing accuracy vs power loss.
The ISL88750 uses the Intersil patented Robust Ripple Regulator (R3™) modulation scheme to provide excellent light-load efficiency and fast dynamic response. It is available in a 32 Ld 4x4mm2 QFN package.
