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.

C/W Notes: 1) Exceeding these ratings may damage the device. 2) The maximum allowable power dissipation is a function of the maximum junction temperature TJ(MAX), the junction-toambient thermal resistance θJA, and the ambient temperature TA. 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 <300µs and duty cycle < 2% 4) Continuous body diode conduction (reverse conduction) is not recommended. 5) Measured on JESD51-7, 4-layer PCB.

The switch operates from 1.7V to 5.5V nominal input voltage and can handle up to 2A continuous load. Enable The logic pin disables the switch to reduce overall supply current .Once the EN pin reaches logic enable threshold, the MP62040/MP62041 is enabled and the supply current is very small, only 2μA. APPLICATION INFORMATION Power-Supply Considerations Over 10μF capacitor between IN and GND is recommended. This precaution reduces powersupply transients that may cause ringing on the input. In order to achieve smaller output load transient ripple, placing a high-value electrolytic capacitor on the output pin(s) is recommended when the load is heavy.
