Advanced Load Management
Controlled Load Switch with Low RON
The NCP4545 load switch provides a component and area-reducing
solution for efficient power domain switching with inrush current
limit via soft start. It is designed to integrate control and driver
functionality with a high performance low on-resistance power
MOSFET in a single device. 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
• Soft−Start via Adjustable Slew Rate Control
• Low On−Resistance
• Input Voltage Range 0.5 V to 6 V
• Low Standby Current
• Load Bleed Function
• No External Components Required
• Enable Pin with CMOS Input Levels
• This is a Pb−Free Device
Typical Applications
• Notebook and Tablet Computers
• Handheld Electronics
• Digital Cameras
• Portable Medical Devices
• Hard Drives
• Peripheral Ports
