NCP4543
ecoSwitcht Advanced Load Management
Controlled Load Switch with Low RON
The NCP4543 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 with ESD Protection • Soft−Start via Adjustable Slew Rate Control • Low On−Resistance • Input Voltage Range 0.
