Advanced Load Management
Controlled Load Switch with Low R_ON
The NCP4552x series of load switches provide a component and
area-reducing solution for efficient power domain switching with
inrush current limit via soft start. These devices are designed to
integrate control and driver functionality with a high performance low
on−resistance power MOSFET in a single package. 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 R_ON
• Input Voltage Range 0.5 V to 13.5 V
• Soft-Start via Controlled Slew Rate
• Adjustable Slew Rate Control (NCP45525)
• Power Good Signal (NCP45524)
• 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
