General Description

The EM5203N is an N-channel MOSFET

high-side power switch without parasitic body

diode between drain and source. The EM5203N

provides very low on-resistance as 58m and

continuously delivers up to 3A output current. The

fault flag output function indicates fault conditions

to the local USB controller. The other features

include soft start, current limit protection,

Power-On-Reset function, and over temperature

protection. The EM5203N is available in MSOP-8

package.
