MP62170/MP62171 3.3V/5V, Single-Channel 1.5A Current-Limited Power Distribution Switch The Future of Analog IC Technology DESCRIPTION FEATURES 1.5A Continuous Current The MP62170/MP62171 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 MP62170/MP62171 90uA Quiescent Current analog switch has 75m on-resistance and 75m 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 MP62170/MP62171 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. SOIC8 & MSOP8 Packages 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 MP62170/MP62171 is available in 8-pin MSOP Set-top-box and SOIC package without exposed pad.
