The STMicroelectronics STPM801 is the market’s first automotive-qualified integrated hot-swap and ideal-diode controller featured for functional-safety applications. The ideal-diode controller drives an external MOSFET replacing a Schottky diode conventionally used for reverse-input protection and output-voltage holdup. The reduced voltage drop across the MOSFET reduces power dissipation during normal operation, compared to the forward voltage of the Schottky diode. When…
