SEOUL -- Samsung Electronics has released two new controller chips which identify power delivery (PD)-certified power sources to fast-charge devices safely.

USB Type-C power delivery (PD) 3.0 is the latest USB specification for fast-charging. It is widely used in the latest generation of laptops, PCs and handheld game consoles. Although a power charger using the USB Type-C PD 3.0 specification would charge non-PD devices but the charging speed will be set to slow mode to protect the lifecycle of batteries.

Samsung Electronics said in a statement on Tuesday that it released two controller chips, MM101 and SE8A, which are capable of identifying whether connected devices are certified with USB Type-C PD 3.0. If the chips find that connected devices are certified, they can supply up to 100 watts, instead of 10 watts supplied by a normal power charger.

"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," Samsung's system LSI marketing senior vice president Ben K. Hur was quoted as saying. He said Samsung's new controller chips can quickly charge devices and establish safeguards against unauthorized access.

While MM101 chips provide an advanced encryption feature using a symmetric encryption algorithm, SE8A chips have the industry's first embedded security system which provides extra security measures protection inside a compact form factor of the chip, Samsung said, adding SE8A chips can be utilized in power chargers which would prevent connected devices from taking vital information from a network they are hooked onto.
