NXP Semiconductors Integrated Load Switches

NXP Semiconductors Integrated Load Switches are feature-rich logic controlled high side load switches that manage the distribution of power in application sub-systems to significantly reduce total power dissipation. Available in extremely small WLCSP packages and with a continuous current as low as 500mA and as high as 3A, NXP Load Switches are suitable for multiple space-constrained applications. Load switches are ideal for use in portable systems to extend battery life and optimize charging cycles.

NXP Load Switches integrate reverse voltage protection, over-voltage protection, over-current protection, and over-temperature protection. These protection features prevent damage to the load switch and the components it supplies when a system fail event is detected. Integrated slew-rate control reduces the inrush current when supplying a sub-system.

Features

Wide input voltage range of 1.1V to 20V for design flexibility
Low R_ON of 20mΩ (typical) for low loss across the switch
Overvoltage tolerant threshold control logic eliminates external level shifters
Integrated resistor to discharge load capacitance when the switch is disabled

Reverse voltage protection
Low power off-leakage current for extended battery life
Under-voltage lockout ensures the switch remains disabled when a voltage less than the operating range is applied
Over-temperature shutdown prevents any damage to switch and downstream peripherals
