MAX1812 - Dual USB Switch with Fault Blanking

General Description

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.

Key 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 (FAULTA and 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.
