ISL88739B
Hybrid Power Boost (HPB) Battery Charger with SMBus Interface
DATA SHORT
To request the full datasheet, please visit www.intersil.com/products/isl88739b
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 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 ISL88739B uses N-channel MOSFETs (NFETs) for
all the switches to achieve the best performance and
lowest BOM cost. The internal charge pump can turn on
all the NFETs quickly or slowly, 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 ISL88739B 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 battery-current
limit in addition to SMBus programmable limits.
The ISL88739B provides a high accuracy adapter current
monitor, battery current monitor, and system power
monitor outputs. Several configurable current-sense
resistor value options provide maximum flexibility for
working with high and low power systems, to achieve the
best trade-off of current sensing accuracy vs power loss.
The ISL88739B uses the Renesas Robust Ripple
Regulator (R3™) modulation scheme to provide
excellent light-load efficiency and fast dynamic response.
It is available in a 32 Ld 4x4mm
2
QFN package.
