NXP Semiconductors Commutateurs d'alimentation côté haut NX5P NXP
Les commutateurs d'alimentation côté haut à contrôle logique NX5P NXP sont des commutateurs de charge intelligents riches en fonctionnalités pour la gestion de l'alimentation. Les commutateurs NX5P protègent les accessoires USB fragiles des niveaux transitoires de tension et d'intensité, fournissent une isolation d'alimentation, réduisent la dissipation d'alimentation sur les solutions LDO et prolongent la durée de vie de la batterie.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.
Caractéristiques
- Wide input voltage range of 1.1V to 20V for design flexibility
- Low RON 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
Applications
- Battery charging control in cell phones
- Power management in battery-operated electronics
- Power supply routing, isolation, and distribution
