Oct 4, 2017 Buck-Boost Narrow VDC Battery Charger with SMBus Interface and USB OTG
The ISL9238 is a buck-boost Narrow Output Voltage DC (NVDC)
chargers. The ISL9238 provides the NVDC charging function,
system bus regulation and protection features for tablet,
ultrabook, notebook, power bank, and any USB-C interface
platform. IntersilвЂ™s advanced R3в„ў Technology is used to
provide high light-load efficiency and fast transient response. Features In Charging mode the ISL9238 takes input power from a wide
range of DC power sources (conventional AC/DC charger
adapters, USB PD ports, travel adapters, etc.) and safely charges
battery packs with up to 4-series cell Li-ion batteries. Autonomous charging option (automatic end of charging) As a NVDC topology charger, it also regulates the system output to
a narrow DC range for stable system bus voltage. The system
power can be provided from the adapter, battery or a combination
of both. The ISL9238 can operate with only a battery, only an
adapter or both connected. For Intel IMVP8 compliant systems
the ISL9238 includes PSYS (System power monitor) functionality,
which provides an analog signal representing total platform
power. The PSYS output will connect to a wide range of Intersil
IMVP8 core regulators to provide an IMVP8 compliant power
domain function. Adapter current and battery current monitor (AMON/BMON) Buck-boost NVDC charger for 1-, 2-, 3-, or 4-cell Li-ion batteries Input voltage range 3.2V to 23.4V (no dead zone) System output voltage 2.4V to 18.304V System power monitor PSYS output, IMVP compliant Up to 1MHz switching frequency PROCHOT# open-drain output, IMVP compliant Allows trickle charging of depleted battery Ideal diode control in Turbo mode Reverse buck, boost and buck-boost operation from battery Two-level adapter current limit available Battery Ship mode option SMBus and auto-increment I2C compatible The ISL9238 supports reverse buck, boost, or buck-boost
operation to input port from 2-to 4-cell batteries. 4x4 32 Ld TQFN package The ISL9238 has serial communication using SMBus/I2C that …
