Dual USB Switch with Fault Blanking  
General Description  
Features  
Dual USB Switch in Tiny 10-Pin µMAX Package  
Guaranteed 500mA Load per Channel  
Built-In 20ms Fault Blanking  
The MAX1812 is a dual current-limited switch specifi-  
cally made for USB applications. Each channel is guar-  
anteed to supply 500mA and meets USB specifications.  
The MAX1812’s low quiescent supply current (45µA)  
and shutdown current (3µA) conserve battery power in  
portable applications.  
Compliant to USB Specifications  
+4.0V to +5.5V Input Voltage Range  
45µA Quiescent Current  
The MAX1812 has multiple safety features to ensure  
that the USB port is protected. Built-in thermal-overload  
protection limits power dissipation and junction temper-  
ature. The device also has accurate internal current-lim-  
iting circuitry to protect the input supply against both  
overload and short-circuit conditions. Independent fault  
signals (FAULTA and FAULTB) notify the microproces-  
sor when a thermal-overload, current limit, undervoltage  
lockout, or short-circuit fault occurs. A 20ms fault-blank-  
ing feature enables the circuit to ignore momentary  
faults, such as those caused when hot-swapping a  
capacitive load, thereby preventing false alarms to the  
host system.  
3µA Shutdown Current  
Independent Shutdown Control  
Independent FAULT Indicator Outputs  
Thermal-Overload Protection  
UL Listing Pending  
The MAX1812 is available in a space-saving 10-pin  
µMAX package. For single versions of this device, refer  
to the MAX1693, MAX1694, and MAX1607 data sheets.
