The IR5001 is a universal high-speed controller and N-channel power MOSFET driver for Active ORing and reverse polarity protection applications. The output voltage of the IR5001 is determined based on the polarity of the voltage difference on its input terminals. In particular, if the current flow through an N-channel ORing FET is from source to drain, the output of the IR5001 will be pulled high to Vcc, thus turning the Active ORing FET on. If the current reverses direction and flows from drain to source (due to a short-circuit failure of the source, for example), the IC will quickly switch the Active ORing FET off. Typical turn-off delay for the IR5001 is only 130nS, which helps to minimize voltage sags on the redundant dc voltage. Both inputs to the IC (INN and INP) as well as Vline input contain integrated high voltage resistors and internal clamps. This makes the IR5001 suitable for applications at voltages up to 100V, and with a minimum number of external components.
