Positive high voltage ideal diode controller. Compared to Schottky diodes, provides lower loss path, more efficient solution in high-power applications, reduces heat dissipation board space need. Inputs and outputs equivalent to diodes. Detects output voltage greater than input (millivolt level) and shuts down output immediately with fast response speed. Features reverse input protection, immediate output shutdown when output voltage exceeds input (millivolt level). Ideal for replacing common high-current diodes, solar panels in parallel, suitable for charging backwash protection.
