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. In addition to integrated control
functionality with ultra low on−resistance, these devices offer system
safeguards and monitoring via fault protection and 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 R
ON
• Input Voltage Range 0.5 V to 13.5 V
• Soft-Start via Controlled Slew Rate
• Adjustable Slew Rate Control (NCP45521)
• Power Good Signal (NCP45520)
• Thermal Shutdown
• Undervoltage Lockout
• Short-Circuit Protection
• 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
