Description
The GWSXXXX is a Dual 12V, 34 mΩ, N-Channel Power Mosfet used
for Li ion battery protection. It is offered in a chip-scale 0.77 mm X 0.77
mm LGA with a very low thickness profile of 0.20 mm. The device uses
Great Wall Semiconductor’s patented Lateral PowerTM CMOS
technology. It has extremely high power density, reducing the board
size of Li Ion Battery power system. Designed for hand held devices
with a high level of ESD protection.
