General Description
The MAX4826–MAX4831 family of switches has internal
current limiting to prevent host devices from being
damaged due to faulty load conditions. These analog
switches have a low 0.7
Ω on-resistance and operate
from a +2.3V to +5.5V input voltage range. These
devices are available with guaranteed 50mA and
100mA current limits, making them ideal for load-
switching applications. In addition to the current-limit
fault flag (FFLG), an open-drain no-load flag indicator
(NOLD) notifies the system when the current through
the switch is less than 10mA (MAX4826–MAX4829), or
5mA (MAX4830/MAX4831).
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 MAX4826/MAX4828/MAX4830 enter a latchoff state
where the switch is turned off, and FFLG is issued to
the microprocessor. The switch can be turned on again
by cycling the power or ON.
The MAX4827/MAX4829/MAX4831 have an autoretry
feature where the switch turns off after the blanking
time, and then continuously checks to see if the over-
load condition is present. The current-limit fault flag
(FFLG) is issued and remains low until after the fault
condition is removed. The switch remains on after the
overload condition disappears.
The MAX4826–MAX4831 operate over the extended
-40°C to +85°C temperature range, and are available in a
tiny space-saving, 1mm x 1.5mm, 6-pin DFN package.
