General Description

The EM5203J/AJ is an N-channel MOSFET

high-side power switch without parasitic body

diode between drain and source. The EM5203J/AJ

provides very low on-resistance as 60m and

continuously delivers up to 2.1A 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 EM5203J/AJ is available in

SOT23-5L package.
