General Description
The MSI2206 is a dual-channel, low Ron N-channel
MOSFET with controlled turn-on.
The input voltage range operates from 0.8V to
5.5VDC and can support a maximum continuous

independently controlled by an EN1 and EN2.
In device, a 220Ω on-chip load resistor is added for
quick output discharge when switch is turned off.
The device is packaged 2mm x 3mm, DFN-14Lead
with thermal pad for high power dissipation.

Detailed Descriptions
Overview
The MSI2206 is a dual channel load switch has low Ron N-
channel MOSFET with controllable slew rate.
The MSI2206 is designed to have very low leakage current
during off state. This prevents downstream circuits from
pulling high standby current from the supply.
The MSI2206 is controlled by active-high logic input the EN
pin. This device has controllable rise time for limiting inrush
current.
The input voltage range operates from 0.8V to 5.5VDC to
support a wide range for using in many kinds of applications.
This device is packaged 2.0 mm x 3.0 mm, DFN-14 lead
package.
Controllable Rise Time
A capacitor to GND on the CT pin sets the slew rate. For
optimal performance, CT cap should be minimum 25V
voltage rating. A chart for relationship between CT and slew
rate when VBIAS is set to 5V is below.

Rise time can be calculated by multiplying the input voltage
by the slew rate.
Quick Output Discharge
The MSI2206 has a Quick Output Discharge (QOD). When
the switch is disabled, a discharge resistor is connected
between VOUT and GND. This resistor has a typical value of
220Ω.
Low Power Consumption
VIN off-state leakage is 0.07uA at 1.8-VIN. So, the load
switch allows system standby power consumption to be
reduced.
Application and Implementation
EN Input
The MSI 2206’s switch position is controlled by an EN
active-high logic input. The switch is on when EN is logic
high and off when EN is logic low.
The EN pin has a low threshold, making it capable of
interfacing with low-voltage signals. The EN pin is
compatible with standard GPIO logic thresholds. It can be
used with any microcontroller with 1.2V or higher GPIO
voltage.
The EN pin does not leave floating, because this pin has no
DEpCu. l2l-0u1p5or down resistance.
Input Capacitor
To limit the voltage drop on the input supply caused by
transient inrush currents or short-circuit, a capacitor needs to
be placed between VIN and GND.
A 1uF ceramic capacitor of CIN is usually sufficient. Input
capacitor is placed close to the pins.
When switching heavy loads, it is recommended to have an
input capacitor about 10 times higher than the output
capacitor to avoid excessive voltage drop.
Output Capacitor
Operation of the MSI2206 is recommended CIN greater than
CL. If CL greater than CIN, VOUT can exceed VIN when system
supply is removed. This could result in current flow from
VOUT to VIN.
A CIN to CL ratio of 10 to 1 is recommended for minimizing
VIN dip caused by inrush currents during startup.
VIN and VBIAS Voltage Range
For optimal operation, make sure VIN≤VBIAS. If setting VIN >
VBIAS, RON is increased steeply.
Thermal and Layout Consideration
The MSI2206 maximum power dissipation depends on the
differences of the thermal resistance and temperature
between junction and ambient air.
The maximum IC junction temperature should be restricted
to 125°C under normal operating conditions. To calculate the
maximum allowable power dissipation, PD(MAX) for a given
output current and ambient temperature, use the following
equation:
P T TD(MAX)
J (MAX )
JA
A
Where:
-PD(MAX) = maximum allowable power dissipation
-TJ(MAX) = maximum allowable junction temperature
(125°C for the MSI2206)
-TA = ambient temperature of the device
-ΘJA = junction to air thermal impedance. See Thermal
Information section. This parameter is highly dependent
upon board layout.
The figure below shows an example of a layout. Notice the
thermal vias located under the exposed thermal pad of the
device. This allows for thermal diffusion away from the
device.
