DATA SHORT ISL95521 FN8771 Rev 2.00 Hybrid Power Boost (HPB) and Narrow VDC (NVDC) Configurations Combo Jul.18.19 Battery Charger with SMBus Interface The ISL95521 is a highly versatile combo battery charger Features configurable for operating as either a Hybrid Power Boost Configurable as an HPB charger or NVDC charger (HPB) charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or 4-cell batteries. Both configurations allow the battery to Compliant with Intel PROCHOT and PSYS requirements work with the adapter together to supply the system load when Adapter current monitor and battery discharging current it exceeds the adapter capability, referred to as system Turbo monitor mode. The HPB charger configuration reverse-boosts battery Uses NFET for all the switches energy to the system bus to help the adapter provide system power in Turbo mode. The NVDC charger configuration quickly - Supports battery removal during battery learn mode turns on BGATE to enable the battery to help the adapter - Actively controlled inrush current to prevent FET damage provide system power in Turbo mode. SMBus programmable settings and high accuracy The ISL95521 uses N-channel MOSFETs (NFETs) for all the Comprehensive protection features switches to achieve the best performance and lowest BOM - PROCHOT indicator for system low voltage, adapter cost. The internal charge pump is capable of turning on all the overcurrent, battery overcurrent, and system overheating NFETs fast or slow depending on the circumstance or the need. The ability to quickly turn on NFETs prevents system bus - Hardware-based adapter current and battery current voltage drop when the battery is suddenly removed in Turbo limits mode or in battery learn mode. - Supports sudden battery removal in system Turbo mode The ISL95521 provides many protection features including a 16 switching frequency options from 350kHz to 1MHz PROCHOT indicator for system low voltage, adapter Low quiescent current overcurrent, battery overcurrent or overheating, with an array 2 SMBus and auto-increment I C compatible of SMBus programmable parameters for maximum flexibility. The ISL95521 also features hardware based adapter current Robust Ripple Regulator (R3) modulation scheme provides limit and battery-current limit in addition to SMBus excellent light-load efficiency and fast dynamic response programmable limits. 32 Ld 4mmx4mm QFN package The ISL95521 provides high accuracy adapter current monitor, Pb-free (RoHS compliant) battery current monitor, and system power monitor outputs. To provide maximum flexibility for working with high power and Applications low power systems, the ISL95521 provides several Devices with rechargeable 2-, 3-, or 4-cell batteries configurable current-sense resistor value options to achieve the best trade-off of current sensing accuracy vs power loss. Related Literature The ISL95521 uses the Renesas Robust Ripple Regulator ISL95521 device page (R3) modulation scheme to provide excellent light-load efficiency and fast dynamic response. The ISL95521 is available in a 32 Ld 4mmx4mm QFN package.
