EM5209
Dual Channel, Ultra-Low Resistance Load Switch
General Description
The EM5209 is a small, ultra-low RON, dual
channel load switch with controlled turn on. The
device contains two N-channel MOSFETs that can
operate over an input voltage range of 0.8V to 5.5V
and can support a maximum continuous current of
6A per channel. Each switch is independently
controlled by an on/off input (ON1 and ON2),
which is capable of interfacing directly with
low-voltage control signals. In EM5209, a 220-Ω
on-chip load resistor is added for quick output
discharge when switch is turned off.
The EM5209 is available in a small,
space-saving DFN3X2 package with integrated
thermal pad allowing for high power dissipation.

Note 1.

Note 3.
Note 4.
Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device.
These are for stress ratings. Functional operation of the device at these or any other conditions beyond
those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may remain possibility to affect device reliability.
θJA is measured in the natural convection at TA=25oC on a 4-layers high effective thermal conductivity test board with
minimum copper area of JEDEC 51-7 thermal measurement standard.
Devices are ESD sensitive. Handling precaution is recommended.
The device is not guaranteed to function outside its operating conditions.
Output Rising Time Control
The table as below contains rise time values measured on a typical device. Rise time shown below are only valid for
the power-on sequence where VIN and VBIAS are already in steady state condition, and the VON is high.
