NPS7601UP

NPS7601UP Production

Compact parallelable 1.5 V to 5.5 V, 1.5 A, low Iq load switch with true reverse current blocking

The NPS7601 is a compact, single-channel, regulated forward-drop load switch with always-on, true reverse current blocking capabilities. It provides efficient switching between power rails, minimizing power loss and enabling precise load control.

The NPS7601 operates across an input voltage range of 1.5 V to 5.5 V, and supports up to 1.5 A of continuous current. An active-high enable (EN) input controls its operation, allowing for isolation of the load by blocking current in both directions when the pin is held low. When EN is asserted high and the input voltage exceeds the output, the NPS7601 turns on in a controlled manner, managing inrush current to prevent voltage droop on the power source.

To achieve fast-acting, true reverse current blocking with minimal transient reverse current, the device utilizes a regulated forward voltage scheme. This active control method overcomes the limitations of common IN-to-OUT voltage comparator-based solutions, which often require hundreds of milliamps before activation.

The NPS7601 is suitable for various applications, including:

  • Power supply sequencing

  • Power supply multiplexing

  • Power supply OR-ing

  • Parallel operation for high-current loads

NPS7601 is offered in a compact WLCSP4 (SOT8113) package and is qualified for operation over an ambient temperature range of -40 °C to 125 °C.

Interactive datasheet

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
