1 / 13 page © Semiconductor Components Industries, LLC, 2015 February, 2015 − Rev. 3 1 Publication Order Number: NCP45540/D NCP45540 ecoSWITCH t Advanced Load Management Controlled Load Switch with Low RON The NCP45540 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 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 RON • Input Voltage Range 0.5 V to 13.5 V • Soft-Start via Controlled Slew Rate • Adjustable Slew Rate Control • Power Good Signal • 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 Figure 1.
