SEOUL, South Korea and
SAN JOSE, Calif., June 26, 2019 /PRNewswire/ -- MagnaChip
Semiconductor Corporation ("MagnaChip" or the "Company") (NYSE:
MX), a designer and manufacturer of analog and mixed-signal
semiconductor products, announced today a new low-Rss(on)* LV (Low
Voltage) MOSFET with reduced chip size for smartphone battery PCMs
(Protection Circuit Modules).
Extended life and increased protection for batteries in high-end
LTE and 5G smartphones are becoming increasingly important.
5G phones, in particular, need longer-lasting batteries with
higher endurance than previous smartphones to process the massive
amount of data with extremely fast download and upload
capabilities. Inserted in the battery PCMs in LTE or 5G
phones, this newly released MOSFET prevents over-voltage and
over-current of the batteries and ultimately helps extend their
life and resolve the overheating issue.
The Rss(on) of this new product, 20 percent lower than previous
versions with the same chip size, prolongs the life of smartphone
batteries by decreasing current loss and improving heat
dissipation. This lower Rss(on) also enables higher-power
density than previous versions to prevent over-heating of the
battery during a quick charge (a feature supported by most of the
latest smartphones). PCM functionality is also enhanced by an
ESD (Electrostatic Discharge) protection diode added to the
product. This diode mitigates ESDs of ≤ 2 kV to strengthen
circuit protection and prevents damage to other smartphone
components.
MagnaChip also has reduced the chip size of this new MOSFET by
10 percent (as compared to other LV MOSFETs currently on the
MagnaChip portfolio), which offers greater design flexibility for
circuit designers and even shrinks the PCM itself. With this
reduction in size, WLCSP (Wafer Level Chip Scale Package) is
possible for this product.
"Quick charging, fast processor speeds and other advanced
specifications for new LTE and 5G smartphones require power
products that provide superlatively high levels of battery
protection," said YJ Kim, CEO of MagnaChip. "We are working
closely with the OEM community to decrease the footprint of our
MOSFETs and incorporate other product enhancements to meet these
objectives."
* Rss(on): On resistance, the resistance value between the drain
and source of a MOSFET during operation (ON)
