MAX869LEEE+
2A, Current-Limited, High-Side P-Channel Switch with Thermal Shutdown
_______________General Description
The MAX869L P-channel load switch features an accu-
rate user-set current limit and low on-resistance. This
switch is designed to protect your power source from
shorts and surges by limiting current and preventing
the system supply from being pulled low. The input volt-
age range is 2.7V to 5.5V.
The MAX869L features a 2A, 45mΩswitch controlled
by a logic signal. Current-limit accuracy is ±21%, and
can be set from 400mA to 2.4A using a single resistor.
The device has a low 12μA quiescent supply current,
which reduces to 2μA max in shutdown. It features ther-
mal-shutdown protection and a logic-signal output pin
(FAULT) that signals when there is an overcurrent or
overtemperature condition.
For other devices in this family, consult the Selector
Guide.

_______________Detailed Description
The MAX869L P-channel MOSFET power switch limits
output current to a programmed level. When the output
current passes through the main switch, a smaller cur-
rent also passes through the replica switch (IOUT / 955)
and through RSET(Figure 1). When the voltage on RSET
exceeds the trip voltage of 1.24V, the current-limit error
amplifier regulates the output current to the pro-
grammed current limit, ILIMIT(400mA to 2.4A).
This switch is not bidirectional; therefore, the input volt-
age must be higher than the output voltage.
Setting the Current Limit
The MAX869L features internal current-limiting circuitry
with a maximum programmable value (IMAX) of 2.4A.
For best performance, set the current limit (ILIMIT)
between 0.2 IMAX≤ILIMIT≤IMAX. This current limit
remains in effect throughout the input supply-voltage
range.
Program the current limit with a resistor (RSET) from
SET to ground (Figure 2) as follows:
ISET= ILIMIT/ 955
RSET= 1.24V / ISET =1,184/ILIMIT
where ILIMITis the desired current limit.A, Current-Limited, High-Side
