Advanced Load Management
Controlled Load Switch with Low RON
The NCP45541 load switch provides a component and area-
reducing solution for efficient power domain switching with inrush
current limit via soft−start. In addition to integrated control
functionality with ultra low on−resistance, this device offers system
monitoring via power good signaling. This cost effective solution is
ideal for power management and hot-swap applications requiring low
power consumption in a small footprint.
Features
• Advanced Controller with Charge Pump
• Integrated N-Channel MOSFET with Low RON
• Input Voltage Range 0.5 V to 13.5 V
• Soft-Start via Controlled Slew Rate
• Adjustable Slew Rate Control
• Power Good Signal
• Extremely Low Standby Current
• Load Bleed (Quick Discharge)
• This is a Pb−Free Device
Typical Applications
• Portable Electronics and Systems
• Notebook and Tablet Computers
• Telecom, Networking, Medical, and Industrial Equipment
• Set−Top Boxes, Servers, and Gateways
• Hot−Swap Devices and Peripheral Ports
