3、產品描寫出

LYF62001 is a high efficiency, synchronous bi-directional buck-boost charger with integrated fast charge protocols. It is a comprehensive and flexible buck-boost charger platform designed for most of fast charging applications with type-C port and PD protocol. It can be programmed to buck charging, boost charging or buck-boost charging. LYF62001 provides I2C interface to communicate with MCU, provides high voltage sensing for battery and BUS terminals, accurate rail-rail current sensing for battery current, BUS current and USB ports currents. It also provides high voltage blocking for CC1, CC2, DP, DM communication signals for all of the USB ports. LYF62001 can work with a general MCU to provide a complete, powerful and flexible buck-boost charging system for all kinds of fast charge application such as power bank, battery packs, or portable energy cubic etc. In charging mode, it steps up or down the input voltage to effectively charge the batteries. LYF62001 supports trickle charging, constant current (CC) charging and constant voltage (CV) charging management. The charging current and charging voltage can be programmed by two 12-bit DAC converters. The LYF62001 features I2C interface, so the user can easily control the charging/discharging mode, and program charging current, charging voltage, output voltage, and output current limits through I2C. It also monitors the status of USB ports and provides two NMOS gate drivers to control the power path independently. User can also use I2C to monitor the status of DC-DC, even the whole system. LYF62001 also provides VMON pin, through which the MCU can monitor VBUS, VBAT voltage, IBUS, IBAT current and the current of each port in real time. All these features simplify the system design and reduce BOM cost for any charging system.The LYF62001 supports under voltage protection, over voltage protection, over current protection, short circuit protection and over temperature protections to ensure system safety under different abnormal conditions.
