MAX1823A - Dual USB Switch

Download the MAX1823A datasheet PDF. This datasheet also covers the MAX1823 variant, as both devices belong to the same dual usb switch family and are provided as variant models within a single manufacturer datasheet.

Description

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.

Features

  • to ensure that the USB port is protected. 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 c.

19-1903; Rev 3; 10/03 MAX1823/MAX1823A/MAX1823B/MAX1823H Dual USB Switch with Fault Blanking and Autoreset General Description 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. The MAX1823 has multiple safety features to ensure that the USB port is protected. Built-in thermal-overload protection limits power dissipation and junction temperature.
