Download the MAX1558H datasheet PDF.
This datasheet also covers the MAX1558 variant, as both devices belong to the same dual 3mm x 3mm 1.2a/programmable-current usb switches family and are provided as variant models within a single manufacturer datasheet.
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.
Key Features
ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperature. Accurate, programmable current-limiting circuitry protects the input supply against both overload and short-circuit 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 b.
Note: The manufacturer provides a single datasheet file (MAX1558_MaximIntegratedProducts.pdf) that lists specifications for multiple related part numbers.

h 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 protectio
