NXP Semiconductors Interruttori di alimentazione a monte NX5P NXP

Gli interruttori di alimentazione a monte a controllo logico NX5P NXP sono interruttori di carico intelligenti ricchi di funzionalità per la gestione della potenza. Gli interruttori NX5P proteggono i delicati accessori USB dai transitori di tensione e corrente, forniscono isolamento da potenza, riducono la dissipazione della potenza nelle soluzioni LDO ed estendono la vita della batteria.

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 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 switch remains disabled when a voltage less than the operating range is applied
  • Over temperature shutdown prevents any damage to switch and downstream peripherals

Applicazioni

  • Battery charging control in cell phones
  • Power management in battery operated electronics
  • Power supply routing, isolation, and distribution
