ISL9237HRZ规格书详情
The ISL9237 is a buck-boost Narrow Output Voltage DC (NVDC)
charger utilizing Intersil’s advanced R3™ Technology to provide
high light-load efficiency, fast transient response and seamless
DCM/CCM transitions for a variety of mobile and industrial
applications.
In Charge mode, the ISL9237 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 3 cells in a series configuration.
ISL9237 supports On-the-Go (OTG) function for 2- and 3-cell
battery applications. When OTG function is enabled, the ISL9237
operates in the reverse Buck mode to provide 5V at the USB port.
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 ISL9237 can operate with only a
battery, only an adapter or both connected. For Intel IMVP8
compliant systems, the ISL9237 includes PSYS 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.
The ISL9237 has serial communication via SMBus/I2C that
allows programming of many critical parameters to deliver a
customized solution. These programming parameters include,
but are not limited to: Adapter current limit, charger current limit,
system voltage setting and trickle charging current limit.
