General Description
The MAX4772/MAX4773 switches feature selectable
internal current limiting to prevent damage to host
devices
due
to
faulty
load
conditions.
The
MAX4772/MAX4773 include a logic input to select a
guaranteed 200mA or 500mA current limit, making them
ideal for SDIO and other load-switching applications.
These analog switches have a low 0.2
on-resistance
and operate from a 2.0V to 4.5V input voltage range.
When the switch is on and a load is connected to the
port, a guaranteed blanking time of 14ms ensures that
the transient voltage settles down. If, after this blanking
time, the load current is greater than the current limit,
the MAX4772 switch is turned off and issues a FLAG to
the microprocessor. The switch can be turned on again
by cycling the power or the ON input.
The MAX4773 has an autoretry feature where the switch
turns off and issues a FLAG to the microprocessor after
the blanking time and then continuously checks to see if
the overload condition is present. The switch remains
on after the overload condition disappears and FLAG
deasserts.
The MAX4772/MAX4773 are available in tiny space-sav-
ing 6-pin SOT23 and 6-pin TDFN (3mm x 3mm) pack-
ages.
