Programmable 4A USB Current-Limited  
Switches with Autoreset and Fault Blanking  
2H/MAX1563  
General Description  
Features  
The MAX1562/MAX1562H/MAX1563 single current-  
limited switches provide up to 4A to power up to eight  
USB ports. They operate from a 4V to 5.5V input  
supply and consume only 40µA of quiescent current  
when operating and only 3µA in shutdown.  
o Programmable Current Limit (1A to 4A) with  
Resistor  
o Autoreset Feature Saves System Power  
o 20ms Fault-Blanking Circuitry  
o Active-High/Low Control Logic  
o Fault-Indicator Output  
o Thermal-Overload Protection  
o Smaller 4mm x 4mm Thin QFN Package (MAX1563)  
o 3µA Shutdown Current  
The MAX1562/MAX1562H/MAX1563s’ autoreset feature  
latches the switch off if the output is shorted, thereby  
saving system power. When the short is removed, the  
switch is reactivated. A fault-blanking feature enables the  
circuit to ignore momentary faults, such as those caused  
when hot swapping a capacitive load, preventing false  
alarms to the host system. Fault blanking also prevents  
fault signals from being issued when the device powers  
up the load.  
The MAX1562/MAX1562H/MAX1563 provide several  
safety features to protect the USB port. Built-in thermal-  
overload protection turns off the switch when the die  
temperature exceeds +160°C. Accurate internal cur-  
rent-limiting circuitry protects the input supply against  
both overload and short-circuit conditions. An open-  
drain fault signal (FAULT) notifies the microprocessor  
when a thermal-overload, current-limit, undervoltage  
lockout (UVLO), or short-circuit fault occurs.

*EP = Exposed pad.  
The MAX1562 has an active-low ON, and the  
MAX1562H has an active-high ON enable input. The  
MAX1563 has a selectable active-high or active-low  
logic-controlled enable. The current limit is pro-  
grammed from 1A to 4A using a resistor.  
The MAX1562/MAX1562H are available in 8-pin SO  
packages and are pin-compatible upgrades to the  
MIC2545A/MIC2549A. The MAX1563 provides the  
same features and higher current performance in a  
smaller 12-pin (4mm x 4mm) Thin QFN package. These  
devices operate over an extended temperature range  
(-40°C to +85°C). An evaluation kit is available to speed  
designs.
