NXP Load Switches and Over-Voltage Protection ICs Simple, efficient, protection and control with smallest footprint NXP’s integrated load switch and OVP families, NX3P/NX5P/NX18P, provide simple and efficient power distribution solutions to reduce system power consumption, while providing robust protection against voltage and current surges. Designed in the smallest packages to address mobile and portable applications, they greatly reduce design complexity and time to market. KEY FEATURES BENEFITS • Low ON resistance for highest efficiency • In-rush current control • Over-voltage tolerant inputs to 30 V • Over-voltage protection (OVP) • Over-current protection (OCP) • Over-temperature protection (OTP) • Reverse current protection (RCP) • Output discharge circuit to remove capacitive load • Integrated 8 kV IEC6100-4-2 (contact) ESD diodes • Protects from over-voltage, over-current surges • Extends battery life by disconnecting unused sub-systems • Replace multiple discretes and LDOs lowering total part count Applications OVP and OCP functions safeguard PMIC and sub-blocks from poorly regulated supplies during charge, and from faulty loads while in OTG mode. •Smart phones/tablet PC’s/notebooks •Digital cameras •Portable medical devices •Other power sensitive applications With very low leakage current, and low ON resistance, NX3P/NX5P/NX18P high-side load switches are ideal to manage power distribution to sub-systems while reducing total power dissipation. Available in extremely small plastic and WLCSP packages, they can provide a continuous current from 200 mA to 3.0 A while operating from -40 to 85ºC. Protection and control Packages NXP’s load switches integrate reverse-current/voltage protection, over-voltage protection, over-current protection and over-temperature protection, actively protecting it and the components it supplies, when a system-fail event is detected. Built in small footprint SOT, leadless QFN, and WLCSP packages,these load switches also integrate ESD IEC610004-2 protection making them ideal for portable applications where board space is at a premium. Requiring minimal external components, the low-pin count further improves crowded layouts, by simplifying routing and eliminate dependencies of intricate line-layout patterns. Integrated slew-rate control reduces inrush current associated with system start-up, while the ILIM-feature limits the maximum switch current. NXP packages are Dark Green, Pb-free, RoHS compliant. Equipped with a low-threshold logic enable input, it can be used with both new and legacy controllers.
