General Description
The MAX4914B/MAX4915A/B/MAX4917A/B family of switch-
es feature internal 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 2.3V
to 5.5V input voltage range. They are available with guaran-
teed 100mA, 200mA, and 300mA 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 that
the transient voltages settle down. If after this blanking
time the load current is greater than the current limit,
the MAX4914B/MAX4915B/MAX4917B latchoff versions
enter a latchoff state where the switch is turned off and
FLAG is issued to the microprocessor. The switch can
be turned on again by cycling the power or the ON pin.
The MAX4915A/MAX4917A have an autoretry feature
where the switch turns off after the blanking time and
then continuously checks to see if the overload condi-
tion is present. The switch turns on and remains on after
the overload condition disappears and
FLAG deasserts.
The MAX4914B is available in the tiny 6-pin DFN
(2mm x 2mm) package, while the MAX4915A/B
and MAX4917A/B are available in both 6-pin DFN
(2mm x 2mm) and space-saving 5-pin SOT23 pack-
ages. These devices operate over the -40°C to +85°C
extended temperature range.
