Benefits of ideal diode & ORing controllers
Power efficiency
Reduce the energy loss from traditional discrete or Schottky diodes with low voltage drop, low IQ and thermal optimization.
Protection
Improve system reliability with comprehensive power path and redundant power supply protection such as reverse polarity protection, reverse current blocking and load dump and surge protection.
Space saving
Optimize your system with scalable controllers or fully integrated ideal diodes featuring an N-FET controller, integrated charge pump or integrated FET.
