Samsung’s Two New USB PD Controllers for Power Adaptors meets Latest USB-PD 3.0 Specifications
Samsung today announced two USB Type-C power delivery (PD) controllers, SE8A and MM101. With the new PD controllers, power chargers are able to communicate with the device to deliver the optimum amount of power for more efficient charging through authorized products. Both chips are built with an embedded Flash (eFlash) that allows the flexibility of modifying its firmware to meet the most up-to-date specifications and are able to supply up to 100 watts (W, 20V / 5A).
Samsung’s SE8A is the industry’s first solution that combines a PD controller and Secure Element (CC EAL5+ equivalent) in a single chip, providing extra measures of protection such as security key storage, and encoding and decoding of sensitive data within a device in a compact form factor. The SE8A supports USB Type-C Authentication, a certificate-based authentication program for USB Type-C chargers and devices that prevents the misuse of unapproved products. With enhanced security, the SE8A opens possibilities for new kinds of content and services that may be exclusive to a certain brand, location or event.
The Samsung MM101 supports a symmetric encryption algorithm, Advanced Encryption Standard (AES), for product authentication and includes moisture sensing capabilities to ensure safer charging conditions. The new PD controllers meet the most recent USB specifications for fast-charging, USB-PD 3.0 that addresses the compatibility and efficiency challenges across different mobile devices as well as other electronics.
By supporting up to a 100W capacity, compared to the general smartphone charger’s 10W, power chargers with Samsung’s PD controllers can be used for a variety of devices other than smartphones such as tablets, laptops and monitors. For additional safety Samsung USB Type-C power delivery (PD) controllers, SE8A and MM101also provide over-voltage protection. The MM101 is currently sampling and the SE8A is in mass production.
