The MAX77960/MAX77961 are high-performance wide-input 3A (MAX77960)/6A (MAX77961) buck-boost chargers with Smart Power Selector™ and operate as a reverse buck converter without an additional inductor, allowing the ICs to power USB on-the-go (OTG) accessories. The devices integrate low-loss power switches and provide high efficiency, low heat, and fast battery charging in a small solution size. The reverse buck has true load disconnect and is protected by an adjustable output current limit. The devices are highly flexible and programmable through I2C configuration or autonomously through resistor configuration.

The battery charger includes the Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start up smoothly when an input source is available even when the battery is deeply discharged (dead battery) or missing. For battery safety/authentication reasons, the ICs can be configured to keep charging disabled, and allow the DC-DC to switch and regulate the SYS voltage. The system processor can later enable charging using I2C commands as appropriate. Alternatively, the ICs can be configured to automatically start charging.

Applications

  • USB Type-C Powered Wide-Input Charging Applications
  • 2- and 3-Cell Battery-Powered Devices
  • Smartphones, Tablets, and 2-in-1 Laptops
  • Medical Devices, Health and Fitness Monitors
  • Digital Still, Video, and Action Cameras
  • Handheld Computers and Terminals
  • Handheld Radios
