Data Short To request the full datasheet, visit the ISL88750 product page. ISL88750 Narrow VDC (NVDC) Battery Charger with SMBus Interface The ISL88750 is a highly versatile Narrow VDC Features (NVDC) battery charger that supports 2-, 3-, or 4-cell Adapter current monitor and battery discharging batteries. It allows the battery to work with the adapter current monitor to supply the system load when it exceeds the Uses NFET for all the switches adapter capability, referred to as system Turbo mode. The ISL88750 quickly turns on BGATE to enable the Supports battery removal during Battery Learn battery to help the adapter provide the system power mode in Turbo mode. Actively controlled inrush current to prevent FET The ISL88750 uses N-channel MOSFETs (NFETs) for damage all the switches to achieve the best performance and SMBus programmable settings and high accuracy lowest BOM cost. The internal charge pump is capable of turning on all the NFETs quickly or slowly Comprehensive protection features include depending on the circumstance or need. The ability to Hardware-based adapter current and battery quickly turn on NFETs prevents system bus voltage current limits drop when the battery is suddenly removed in Turbo Supports sudden battery removal in system Turbo mode or in Battery Learn mode. mode The ISL88750 features hardware based adapter 16 switching frequency options from 350kHz to current limit and battery-current limit in addition to 1MHz SMBus programmable limits. Low quiescent current The ISL88750 provides a high accuracy adapter 2 current monitor and battery discharging current SMBus and auto-increment I C compatible monitor outputs. To provide maximum flexibility for Robust Ripple Regulator (R3) modulation scheme working with high power and low power systems, it provides excellent light-load efficiency and fast provides several configurable current-sense resistor dynamic response value options to achieve the best trade-off of current 32 Ld 4mmx4mm QFN package sensing accuracy vs power loss. Pb-free (RoHS compliant) The ISL88750 uses the patented Robust Ripple Regulator (R3) modulation scheme to provide Applications excellent light-load efficiency and fast dynamic response. The ISL88750 is available in a 32 Ld Devices with rechargeable 2-, 3-, or 4-cell batteries 4mmx4mm QFN package.
