MP62061DH-LF

MP62061 3.3V/5V, Single-Channel 700mA Current-Limited Power Distribution Switch The Future of Analog IC Technology DESCRIPTION FEATURES The MP62061 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62061 Analog switch features 80mΩ 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 MP62061 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. The MP62061 is available in MSOP8E and SOIC8E packages. 700mA Continuous Current 1A Accurate Current Limit 2.7V to 5.5V Supply Range 140uA Quiescent Current 80mΩ MOSFET Thermal-Shutdown Protection Under-Voltage Lockout 8ms FLAG Deglitch Time No FLAG Glitch During Power Up Reverse Current Blocking MSOP8E and SOIC8E packages UL Recognized: E322138 APPLICATIONS • • • • Smartphone and PDA Portable GPS Device Set-top-box USB Power Distribution “MPS” and “The Future of Analog IC Technology” are Registered Trademarks of Monolithic Power Systems, Inc.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) Measured on JESD51-7 4-layer PCB www.MonolithicPower.com MPS Proprietary Information.
