On Tuesday, May 28, Samsung Electronics announced its two new USB Type-C power delivery (PD) controller chips, namely SE8A and MM101. The PD controllers promise optimum power delivery for smartphones, tablets, laptops, and other gadgets.
According to an article released on Samsung Newsroom, the new chip controllers will enable secure, fast-charging up to 100W (20V/5A), which is 10x than the usual 10W of a typical smartphone charger. Both PD controllers are also said to support the most recent USB specifications for fast-charging, the USB-PD 3.0.
“In addition to smarter features and larger batteries, innovative charging solutions allow us to do more through our mobile devices today. Following this trend, power adapters that can quickly charge devices while establishing safeguards against unauthorized access are increasingly in demand,” said Ben K. Hur, Senior Vice President of System LSI Marketing at Samsung Electronics.
“Samsung’s power delivery MM101 and security-enhanced SE8A will not only make charging faster and safer but also enable new services that can enrich tomorrow’s mobile experiences,” he added.
Both chips are built with an embedded Flash (eFlash) feature that allows the flexibility of delivering firmware updates and are also granted with protective feature against over-voltage.
Samsung’s SE8A stands as the first power delivery controller in the industry that is imbued with Secure Element (CCEAL5+ equivalent). This indicates added protection against unauthorized charges. The said type of PD controller also supports USB Type-C Authentication, which prevents the misapplication of unapproved products. “With enhanced security,” Samsung explained, “the SE8A opens possibilities for new kinds of content and services that may be exclusive to a certain brand, location or event.”
On the other hand, the MM101 is said to support asymmetric encryption algorithm, the Advanced Encryption Standard (AES). This allows product authentication and ensures safer charging conditions through moisture sensing capabilities.
SE8A is now being mass-produced and is expected to appear in the market first, while MM101 is still being sampled by clients.
Once they hit the market, Samsung’s new PD controller chips will serve as the first 100W charging designed for smartphones. This follows Xiaomi’s earlier debut of its own 100W fast charge technology on the Mi Mix 4, which promises instant power-up in just 17 minutes.
Many believe that the electronics giant will be including its 100W charger on its Galaxy Note 10, which is expected to be launched later this year.
