ISL95521A  
FN8841  
Rev 2.00  
Jul.19.19  
Hybrid Power Boost (HPB) and Narrow VDC (NVDC) Combo Battery Charger with  
SMBus Interface  
The ISL95521A is a highly versatile combo battery charger  
Features  
configurable for operating as either a Hybrid Power Boost (HPB)  
• Configurable as HPB charger or NVDC charger  
charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or  
4-cell batteries. Both configurations allow 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. The  
HPB charger configuration reverse-boosts battery energy to the  
system bus to help the adapter provide the system power in Turbo  
mode. The NVDC charger configuration quickly turns on BGATE to  
enable the battery to help the adapter provide the system power  
in Turbo mode.  
• Compliant with Intel PROCHOT# and PSYS requirements  
• Adapter current monitor and battery discharging current  
monitor  
• Uses NFET for all the switches  
- Supports battery removal during Battery Learn mode  
- Actively controlled inrush current to prevent FET damage  
• SMBus programmable settings and high accuracy  
• Comprehensive protection features:  
The ISL95521A 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.  
- PROCHOT# indicator for system low voltage, adapter  
overcurrent, battery overcurrent, and system overheating  
- Hardware-based adapter current and battery current  
limits  
- Supports sudden battery removal in system Turbo mode  
The ISL95521A provides many protection features including a  
PROCHOT# indicator for system low voltage, adapter overcurrent,  
battery overcurrent or overheating, with an array of SMBus  
programmable parameters for maximum flexibility. It also  
features hardware based adapter current limit and  
• 16 switching frequency options from 350kHz to 1MHz  
• Low quiescent current  
2
• SMBus and auto-increment I C compatible  
• Robust Ripple Regulator (R3) modulation scheme provides  
excellent light-load efficiency and fast dynamic response  
battery-current limit in addition to SMBus programmable limits.

The ISL95521A provides a high accuracy adapter current  
monitor, battery current monitor, and system power monitor  
outputs. To provide maximum flexibility for working with high  
power and low power systems, the ISL95521A provides  
several configurable current-sense resistor value options to  
achieve the best trade-off of current sensing accuracy vs power  
loss.  
• 32 Ld 4x4mm QFN package  
• Pb-free (RoHS compliant)  
Applications  
• Devices with rechargeable 2-, 3-, or 4-cell batteries
