MP6231/MP6232 3.3V/5V, Dual-Channel 500mA Current-Limited Power Distribution Switches The Future of Analog IC Technology DESCRIPTION FEATURES 500mA Continuous Current The MP6231/MP6232 Power Distribution Accurate Current Limit Switch features internal current limiting to 2.7V to 5.5V Supply Range prevent damage to host devices due to faulty load conditions. The MP6231/MP6232 analog 140 A Quiescent Current switch has 85m on-resistance and operates 85m MOSFET from 2.7V to 5.5V input. It is available with Thermal-Shutdown Protection guaranteed current limits, making it ideal for Under-Voltage Lockout load switching applications. The 8ms FLAG Deglitch Time MP6231/MP6232 has built-in protection for both No FLAG Glitch During Power Up over current and increased thermal stress. For Reverse Current Blocking over current, the device will limit the current by Active High & Active Low Options changing to a constant current mode. UL File E322138 As the temperature increases as a result of APPLICATIONS short circuit, then the device will shut off. The Smartphone and PDA device will recover once the device temperature Portable GPS Device reduces to approx 120 C. Notebook PC The MP6231/MP6232 is available in 8-pin Set-top-box MSOP, SOIC package with exposed pad.
