NPS4001GVH

NPS4001GVH is a 5.5V, 55mohm load switch suitable for applications up to 2A. The NPS4001 switch limits the output current to a constant current by using a constant-current mode when the output load exceeds the current limit threshold or shorted. An internal voltage comparator disables the load switch when the output voltage is higher than the input to protect devices on the input side of the switch. The FLG pin is an active low output to indicate overcurrent, over temperature, and reverse voltage conditions. Applications include USB ports/hubs, laptops, docking station and desktops, set top box, HDTV, optical socket protection, current limiting circuits.

• Input operating voltage range from 2.5V to 5.5V
• Constant current during current limit
• No body diode when disabled (no current path from pin OUT to pin IN)
• Active reverse voltage protection
• Built in soft start, UL 62368 recognition
• Drain-source on-state resistance is 55mohm typical at (VIN= 5.5V, Tamb = -40°C to +125°C)
• ON/OFF input current is 0.5uA maximum at (VON = 0V or 5.5V)
• Quiescent current is 285µA maximum at (VIN = VON= 5.5V; no load on pin OUT)
• Shut down current is 1µA maximum at (VIN = 5.5V; no load on pin OUT, VON = 0V)
• Operating temperature range from -40°C to +125°C, SOT753 package
