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 is removed. Each channel is guar-  
anteed to supply 720mA and meet USB specifications.  
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  
ꢀ Blocks Reverse Current in Shutdown  
(MAX1823A/MAX1823B)  
The MAX1823 has multiple safety features to ensure  
that the USB port is protected. Built-in thermal-overload  
protection limits power dissipation and junction temper-  
ature. Accurate internal current-limiting circuitry pro-  
tects 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 ignores momentary faults, such  
as those caused when hot swapping a capacitive load,  
preventing false alarms to the host system. The  
MAX1823A/MAX1823B also block reverse current (cur-  
rent from OUT_ to IN_) while in shutdown.  
ꢀ 4V to 5.5V Input Voltage Range  
ꢀ Independent Shutdown Control  
(MAX1823/MAX1823A—Active Low)  
(MAX1823B/MAX1823H—Active High)  
ꢀ Independent FAULT Indicator Outputs  
ꢀ Thermal-Overload Protection  
ꢀ 50µA Quiescent Current (Both Switches On)  
ꢀ 3µA Standby Current  
ꢀ UL Recognized  
The MAX1823 is available in a space-saving 10-pin  
µMAX package. The MAX1823/MAX1823A are enabled  
with an active-low signal, and the MAX1823B/MAX1823H  
are enabled with an active-high signal. For a single ver-  
sion of this device, refer to the MAX1946 data sheet. For  
a triple version, refer to the MAX1940 data sheet.
