Dual, 3mm x 3mm, 1.2A/Programmable-Current
USB Switches with Autoreset
General Description
The MAX1558/MAX1558H are dual, current-limited
switches with autoreset for USB applications. Autoreset
latches the switch off if it is shorted for more than 20ms,
saving system power. The shorted output is then tested
to determine when the short is removed to automatically
restart the channel. Each channel delivers up to 1.2A
and meets all IEC specifications for USB ports. Low
quiescent supply current (45µA) and standby current
(3µA) conserve battery power in portable applications.
The MAX1558/MAX1558H safety features ensure that the
USB port is protected. Built-in thermal-overload protection
limits power dissipation and junction temperature.
Accurate, programmable current-limiting circuitry pro-
tects the input supply against both overload and short-cir-
cuit conditions. 20ms fault blanking enables the circuit to
ignore transient faults, such as those caused when hot
swapping a capacitive load, preventing false alarms to
the host system. The MAX1558/MAX1558H also feature
reverse-current protection circuitry to block current flow
from the output to the input when the switches are off.
The MAX1558/MAX1558H are available in space-sav-
ing 3mm x 3mm, 10-pin TDFN packages. The MAX1558
is enabled with an active-low signal, and the
MAX1558H is enabled with an active-high signal.

Note 1:
Reverse current (current from OUT_ to IN_) is blocked when disabled.
Note 2:
Forward current (current from IN_ to OUT_) is internally limited. Reverse current, from OUT_ to IN_, is not limited when the
device is enabled and must be kept below 1.5A
RMS
to prevent permanent device damage. When the MAX1558/MAX1558H
are disabled, the switch turns off and reverse current is internally blocked.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
