This change has created a need for greater power delivery via USB-C PD and higher power charging (25W or more). With the MAX77958 USB-C PD controller, designers can now reduce development time by three months with a ready-to-use USB-C PD-compatible solution, while also halving the solution's size with the MAX77962 down-pull charger.
MAX77958: While USB-C PD systems are capable of meeting the demands of next-generation medical, industrial, and portable consumer electronics, compliance with these USB-C specifications requires multiple components and custom firmware that can take several months to develop. The standalone USB-C PD controller MAX77958 saves three months of design, development, and testing time with a ready-to-use USB-C PD 3.0-compliant solution with Fast Role Swap and Dual Role Port (DRP) support. The MAX77958 includes features not typically found in traditional USB-C controllers, such as BC1.2 detection and an integrated D+/D- switch for legacy USB port compatibility. To enable robust designs, the IC features 28V VBUS rating, DC pin short-circuit protection, humidity detection, and corrosion prevention.
MAX77962: New USB-C PD systems enable fast charging of 2S Li+ batteries using an input voltage of 5V to 20V. The MAX77962 integrates high-voltage FETs (30V absolute maximum voltage) capable of delivering 28W of charging power in half the size of other 28W solutions. This buck-boost charger accepts an input voltage range of 3.5V to 23V, compatible with USB-C PD and legacy USB sources.
The MAX77962 step-down charger and MAX77958 USB-C PD controller are suitable for applications such as game players, augmented reality/virtual reality (AR/VR) devices, cameras, wireless speakers, portable printers and handheld computers, as well as industrial equipment and medical devices.
