Nexperia NPS7601 Single-Channel Low IQ Load Switch
Nexperia NPS7601 Single-Channel Low IQ Load Switch is a 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 Nexperia NPS7601 operates across an input voltage range of 1.5V to 5.5V, and supports up to 1.5A of continuous current. An active-high enable (EN) input controls 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 voltage, 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 uses 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.
