MP62340/MP62341 3.3V/5V, Dual-Channel 1A Current-Limited Power Distribution Switches The Future of Analog IC Technology DESCRIPTION FEATURES 1A Continuous Current The MP62340/MP62341 Power Distribution Accurate Current Limit Switch features internal current limiting to prevent damage to host devices due to faulty 2.7V to 5.5V Supply Range load conditions. The MP62340/MP62341 140 A Quiescent Current analog switch has 80m on-resistance and 80m MOSFET operates from 2.7V to 5.5V input. It is available Thermal-Shutdown Protection with guaranteed current limits, making it ideal Under-Voltage Lockout for load switching applications. The 8ms FLAG Deglitch Time MP62340/MP62341 has built-in protection for No FLAG Glitch During Power Up both over current and increased thermal stress. Reverse Current Blocking For over current, the device will limit the current Active High & Active Low Options by changing to a constant current mode. Available is MSOP8E and SOIC8 As the temperature increases as a result of UL ApprovedE322138 short circuit, then the device will shut off. The APPLICATIONS device will recover once the device temperature PDAs reduces to approx 120 C. Portable GPS The MP62340/MP62341 is available in 8-pin Notebook PC MSOP package with exposed pad and SOIC Set-top-box package without exposed pad.
