Dual USB Switch with Fault  
Blanking and Autoreset  
General Description  
Features  
ꢀ Dual USB Switch in Tiny 10-Pin µMAX Package  
ꢀ Autoreset Feature Saves Power  
The MAX1823 is a dual, current-limited switch with  
autoreset specifically made for USB applications. The  
autoreset feature latches the switch off if the output is  
shorted, saving system power. The switch reactivates  
when the short-circuit condition is removed. Each channel  
is guaranteed to supply 720mA and meet USB specifica-  
tions. The device’s low quiescent supply current (50µA)  
and standby current (3µA) conserve battery power in  
portable applications.  
ꢀ Guaranteed 720mA Load per Channel  
ꢀ Built-In 20ms Fault Blanking  
ꢀ Compliant to USB Specification  
ꢀ 4V to 5.5V Input Voltage Range  
ꢀ Independent Shutdown Control  
(MAX1823—Active Low)  
The MAX1823 has multiple safety features to ensure that  
the USB port is protected. Built-in thermal-overload pro-  
tection limits power dissipation and junction temperature.  
The device also has accurate internal current-limiting cir-  
cuitry to protect the input supply against both overload  
and short-circuit conditions. Independent fault signals  
(FAULTA and FAULTB) notify the microprocessor (µP)  
when a thermal-overload, current-limit, undervoltage  
lockout (UVLO), or short-circuit fault occurs. A 20ms  
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.  
(MAX1823H—Active High)  
ꢀ Independent FAULT Indicator Outputs  
ꢀ Thermal-Overload Protection  
ꢀ 50µA Quiescent Current (Both Switches On)  
ꢀ 3µA Standby Current  
ꢀ UL Listing Pending  
The MAX1823 is available in a space-saving 10-pin  
µMAX. The MAX1823 is enabled with an active-low signal  
and the MAX1823H is enabled with an active-high signal.  
For a dual switch without autoreset, refer to the MAX1812  
data sheet. For single versions of this device, refer to the  
MAX1693, MAX1694, and MAX1607 data sheets.
