Key Featrues
Integrated Current-Sensing Circuit and MOSFET Pass Element: This feature reduces the need for external components, lowering the overall system cost and simplifying the design. It enhances efficiency by integrating essential charging elements into a single IC.
Proprietary Die Temperature Regulation Control: Ensures safe charging by regulating the die temperature up to +115°C, allowing maximum charging current without damaging the IC. This improves reliability and extends the lifespan of the battery and charger.
Wide Input Voltage Range with Over-Voltage Protection: Supports an input voltage range of 4.25V to 28V, with protection above +7V to safeguard against unqualified or faulty AC adapters. This feature enhances safety and compatibility with various power sources.
Programmable Fast-Charge Current (up to 1ARMS): Allows customization of the charging current to suit different battery capacities and use cases, optimizing charging speed and efficiency for devices like smartphones, cameras, and MP3 players.
Low Dropout Voltage (300mV at 500mA): Minimizes power dissipation during charging, improving energy efficiency and reducing heat generation, which is particularly beneficial for compact and portable devices.
