General Description
The EM5203 series is an N-channel MOSFET
high-side power switch without parasitic body
diode between drain and source. The EM5203AJ-20
provides very low on-resistance as 60m and
continuously delivers up to 1.5A 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 EM5203 series is available in
SOT23-3, SOT23-5 and DFN1.8X2.0-06 package.
