Features

AI Translation
  • 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 guaranteed to supply 720mA and meet USB specifications.
  • Low quiescent supply current (50μA) and standby current (3μA) conserve battery power in portable applications.
  • Built-in thermal-overload protection limits power dissipation and junction temperature.
  • Accurate internal current-limiting circuitry protects 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, undervoltagelockout (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 (current from OUT_ to IN_) while in shutdown.
  • 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.
  • Dual USB Switch in Tiny 10-Pin µMAX Package
  • Autoreset Feature Saves Power
  • Guaranteed 720mA Load per Channel
  • Built-In 20ms Fault Blanking
  • Compliant to USB Specification
  • Blocks Reverse Current in Shutdown (MAX1823A/MAX1823B)
  • 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
