Renesas Electronics Corporation Buck-Boost Narrow VDC Battery Charger with SMBus Interface and USB OTG ISL9238HRTZ-TK

Description
The ISL9238 is a buck-boost Narrow Output Voltage DC (NVDC) charger. The ISL9238 provides the NVDC charging , system bus regulation and protection features for tablet, Ultrabook, notebook, power bank, and any USB-C interface platform. The advanced Renesas R3™ Technology provides high light-load efficiency and fast transient response. 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. 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 connects to a wide range of IMVP8 core regulators to provide an IMVP8 compliant power domain function. The ISL9238 supports reverse buck, boost, or buck-boost operation to input port from 2- to 4-cell batteries. The ISL9238 has serial communication using SMBus/I2C that allows programming of many critical parameters to deliver a customized solution.
