MP6231DH-LF

MP6231/MP6232 3.3V/5V, Dual-Channel 500mA Current-Limited Power Distribution Switches The Future of Analog IC Technology DESCRIPTION FEATURES The MP6231/MP6232 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP6231/MP6232 analog switch has 85mΩ on-resistance and operates from 2.7V to 5.5V input. It is available with guaranteed current limits, making it ideal for load switching applications. The MP6231/MP6232 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, then 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 140μA Quiescent Current 85mΩ MOSFET Thermal-Shutdown Protection Under-Voltage Lockout 8ms FLAG Deglitch Time No FLAG Glitch During Power Up Reverse Current Blocking Active High & Active Low Options UL File # E322138 APPLICATIONS • • • • • • • The MP6231/MP6232 is available in 8-pin MSOP, SOIC package with exposed pad and 8pin SOIC w/o exposed pad.

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.
