GWS4621L

DATASHEET GWS4621L FN8784 Rev.2.00 Jun 20, 2017 Dual 20V N-Channel Power MOSFET The GWS4621L is a dual 20V, 8.8mΩ, N-channel power MOSFET used for Li-ion battery protection. It is offered in a 1.85mmx1.85mm LGA with a very low thickness profile, 0.29mm typical thickness. It has extremely high power density, reducing the board size of the Li-ion battery power system. Designed for handheld devices with a high level of ESD protection. Features • Monolithic dual MOSFET • Low rDS(ON) in a small footprint • Ultra low gate charge and figure of merit • LGA chip scale package • Low thermal resistance Applications PRODUCT SUMMARY V(BR)SSS ID = 250µA 20V Minimum • Li-ion battery protection rDS(ON) VGS = 4.5V 8.8mΩ Typical • Portable devices, cell phones, PDA • Rated for short-circuit and overcurrent protection • Integrated G-S diodes provide ESD protection of 2.5kV HBM FET1 Gate1 Gate2 Source1 Source2 FIGURE 1.
