450mA/500mA Current-Limit Switches
General Description
The MAX4795–MAX4798 family of switches feature inter-
nal current limiting to prevent damage to host devices
due to faulty load conditions. These analog switches
have a low 0.2Ω on-resistance and operate from a 2.0V
to 4.5V input voltage range. They are available with guar-
anteed 450mA and 500mA current limits, making them
ideal for SDIO and other load-switching applications.
When the switch is on and a load is connected to the
port, a guaranteed blanking time of 14ms ensures the
transient voltages settle down. If after this blanking time,
the load current is greater than the current limit, the
MAX4795 and MAX4797 switches are turned off and
FLAG
is issued to the microprocessor. The switch can be
turned on again by cycling the power or the ON input.
The MAX4796 and MAX4798 have an autoretry feature
where the switch turns off and issues a
FLAG
to the
microprocessor after the blanking time and then contin-
uously checks to see if the overload condition is pre-
sent. The switch remains on after the overload condition
disappears and
FLAG
deasserts.
The MAX4795–MAX4798 are available in tiny, space-
saving, 5-pin SOT23 and 6-pin TDFN (3mm x 3mm)
packages.
