100W USB Type-C® 充电宝参考设计
这是通过 USB 认证的单端口充电宝参考设计。 它可以串联 2 至 4 节电池(默认为 3 节电池),该板上具有电池监控功能。 当与锂离子电池结合时,该参考可以实现充电宝功能。
USB Type-C® 端口具有双角色电源角色 (DRP) 功能,支持为电池充电的受电模式(Sink)和支持可编程电源 (PPS) 的供电模式(Source)...
Buck-Boost Narrow VDC Battery Charger with SMBus Interface and USB OTG The ISL9238C is a buck-boost Narrow Output Voltage DC (NVDC) charger. The ISL9238C provides NVDC charging, system bus regulation, and protection features for tablets, Ultrabooks, notebooks, power banks, and any USB-C interface platform. The advanced Renesas R3™ technology provides high light-load efficiency and fast transient response. In Charging mode, the ISL9238C accepts input power from a wide range of DC power sources (such as conventional AC/DC charger adapters, USB PD ports, and travel adapters) and safely charges battery packs with up to 4-series cell Li-ion batteries. As an NVDC topology charger, the ISL9238C also regulates the system output to a narrow DC range for stable system bus voltage. System power can be provided from the adapter, battery, or a combination of both. The ISL9238C can operate with only a battery, only an adapter, or with both connected. For Intel IMVP8 compliant systems, the ISL9238C includes PSYS (system power monitor) functionality, which provides an analog signal representing total platform power. The PSYS output connects to a wide range of Renesas IMVP8 core regulators to provide an IMVP8 compliant power domain function. The ISL9238C supports reverse buck, boost, or buck-boost operation to the input port from 2- to 4-cell batteries. The ISL9238C provides SMBus/I2C serial communication that allows programming of many critical parameters to deliver a customized solution.
