Sep 7, 2017 Hybrid Power Boost (HPB) Battery Charger with SMBus Interface Features The ISL88739B is a highly versatile battery charger
configurable as a Hybrid Power Boost (HPB) charger,
supporting 2-, 3-, or 4-cell batteries. The configuration
allows the battery to work with the adapter 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. • Configurable as HPB charger
• 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 The ISL88739B 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 quickly or slowly, depending on
the circumstance or the need. The ability to quickly turn
