MP6205DH-LF

MP6205 3.3V/5V, Single-Channel 500mA Current-Limited Power Distribution Switch The Future of Analog IC Technology DESCRIPTION FEATURES The MP6205 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP6205 Analog switch features 90mΩ on-resistance and operates from 2.7V to 5.5V input. It is available with a guaranteed current limit, making it ideal for load switching applications. The MP6205 has built-in protection for both over current and increased thermal stress. For over current, the device will limit the current by changing to a constant current mode. • • • • • • • • • • • • As the temperature increases as a result of short circuit, the device will shut off. The device will recover once the device temperature reduces to approx 120°C. 500mA Continuous Current Accurate Current Limit 2.7V to 5.5V Supply Range 140uA Quiescent Current 90mΩ MOSFET Thermal-Shutdown Protection Under-Voltage Lockout 8ms FLAG Deglitch Time No FLAG Glitch During Power Up Reverse Current Blocking QFN8, MSOP8E, SOIC8E Packages UL Recognized: E322138 APPLICATIONS • • • • The MP6205 is available in QFN8, MSOP8E, SOIC8E packages.
