MAX8586
Single 1.2A USB Switch in
3mm x 3mm TDFN
General Description
The MAX8586 single current-limited switch controls up to
1.2A to power USB applications and has multiple protec-
tion features including thermal shutdown, internal current
limiting, and reverse current protection. The thermal shut-
down limits junction temperature during a prolonged
short or overload condition. The internal current-limiting
circuitry protects the input supply against overload and
is programmable using an external resistor. The
MAX8586 meets all IEC specifications for USB ports.
The IC latches off when the output experiences a short
circuit for more than 20ms, saving system power. Auto-
restart tests the shorted output with a 25mA current to
determine if the short still exists. Once the short is
removed, the MAX8586 automatically restarts the out-
put. An open-drain fault signal notifies the system that
the internal current limit has been reached. A 20ms
fault-blanking feature allows the circuit to ignore
momentary faults such as those caused when hot-
swapping into a capacitive load. An ENRESET input is
available to disable the auto-restart function.
The MAX8586 features a SEL input that programs ON
to be either active high or active low. The IC is supplied
in a space-saving, 8-pin, 3mm x 3mm TDFN package.
