MP62040DQFU-LF-Z

MP62040/MP62041 1.7V – 5.5V, Ultra-Small, Single-Channel 2A Current-Limited Power Distribution Switch The Future of Analog IC Technology DESCRIPTION FEATURES The MP62040/MP62041 Power Distribution Switch is designed for high-side load switch. The switch operates from 1.7V to 5.5V nominal input voltage and includes an 85mΩ power MOSFET to handle up to 2A continuous load.        The MP62040/MP62041 has slew rate control with 115μs rising time to limit inrush current when enabling the switch. The built-in level shift function allows a logic signal on enable input that may be different from the supply voltage to switch the high side P-channel MOSFET ON or OFF. The MP62040/MP62041 is available in an ultrasmall UTQFN4 package, with ultra-low height (0.55mm typ). 2A Continuous Current 1.7V to 5.5V Supply Range Soft Start: 115μs 1μA Shutdown Current 85mΩ MOSFET Active High & Active Low Options Space saving 1.6x1.2 mm UTQFN4 Package (0.55mm Height) APPLICATIONS    Load switch in portable applications Battery switch-over circuits Level translator For MPS green status, please visit MPS website under Quality Assurance. “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) Pulse width
