General Description
The MAX4766 is a programmable current-limit switch
that uses a proprietary control topology to provide a
±10% accurate current limit. It operates from 2.25V to
4.5V input voltage.
The current limit is resistor settable from 0.075A to 1.5A
and features an adjustable soft-start function to control
the output-voltage ramp rate, thereby limiting the inrush
current. It also has an adjustable blanking time to
accommodate various capacitive loads.
If the load current is greater than the current-limit
threshold, the current limiter handles the overcurrent
situation in one of three ways depending on the option
selected. It enters an autoretry mode (MAX4766A),
latches off the switch (MAX4766B), or places the
device in a continuous current-limit mode (MAX4766C).
Additional safety features include thermal shutdown to
prevent overheating and reverse-current blocking to
prevent current from being driven back into the source.
The MAX4766 is available in a tiny 8-pin 3mm x 3mm
TDFN package and operates over the extended tem-
perature range of -40
°
C to +85
°
C.
