MP62055EJ-LF-Z

MP62055 3.3V/5V, Single-Channel 500mA Current-Limited Power Distribution Switch DESCRIPTION FEATURES The MP62055 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62055 analog switch features 115mΩ 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 MP62055 has builtin 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 MP62055 is available in a TSOT23-5 package. 500mA Continuous Current Accurate Current Limit 2.7V to 5.5V Supply Range 90uA Quiescent Current 115mΩ MOSFET Thermal-Shutdown Protection Under-Voltage Lockout 8ms FLAG Deglitch Time No FLAG Glitch During Power Up Reverse Current Blocking TSOT23-5 Package UL File # E322138 APPLICATIONS     Smartphone and PDA Portable GPS Device Set-top-box USB Power Distribution All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.

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. Patent Protected.
