The imminent launch of the Samsung Samsung S20 launches the latest generation of Korean maker phones deal with a good portion of industry news. Today we knew that phones included the manufacturer's first secure chip, its Safe Element, and we watched the video with the disc and the Samsung Galaxy S20 Ultra assembly.
It's now an opportunity for the phone's power system, because the first to arrive certified with the USB PD PPS standard, or a standard that shows how a system of energy must work. The standard had a period of time, about three years, but now officially reaches the mobile ecosystem. Let's take a look at what it contains.
What is USB PPS
Mobile phone users never stop demanding greater autonomy with their phones, but that is an earlier conflict with recommendations received by the smallest and smallest termnals. Therefore, the manufacturer has opted for a more advanced system, offering faster charging systems to restore power to phones more quickly, even though these systems have some basic problems: the higher the power, the more warm the instrument will be and, therefore, immediate destruction of batteries.
To try to avoid this, the USB assembly introduced the PPS standard on USB PD 3.0 certification, or USB Power Delivery 3.0, the standard charging Google has long needed to be considered standard. This certification was introduced in 2017, by the way, or has yet to officially reach the phones until 2020 begins to board the Galaxy S20.
Usually, mobile phone chargers offer a power transmission range rated in volts and amps, which increases the conversion to watts. This means we have minimums and maximum that the charger supports
With standard PPS, either Structured Energy Source which translates as Adjustable power supply, we go to different voltage to protect the phone's health, and the safety of its users. "The announcement of the release of the Samsung Samsung S20 series is one of the broader benefits offered by the USB-IF Certified USB charging Initiative offering to the mobile industry, incorporating reliable USB charging capabilities.
To take advantage of the dynamic PPS load, you must have a standard charger
Because of this PPS standard, compatible devices, both mobile phones and chargers, exchange information on the status of power requirements at all times. Specifically, it does exchanging data every 10 seconds, so that the differences in the delivery are stronger. Therefore, the voltage of this PPS load goes between 3V and 21V, with hops of 0.02 volts.
So PPS will allow lower the device temperature during the charging process, as well as preventing excess power from the charger side, which was stopped by this constant data exchange over the charger's own security mechanisms.
