The MAX1812 is a dual current-limited switch specifically made for USB applications. Each channel is guaranteed 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.
The MAX1812 has multiple safety features to ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperature. The device also has accurate internal current-limiting circuitry to protect the input supply against both overload and short-circuit conditions. Independent fault signals (active-low FAULTA and active-low FAULTB) notify the microprocessor when a thermal-overload, current limit, undervoltage lockout, 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, thereby preventing false alarms to the host system.
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.
