Working Principles

The LTC4415EDHC#PBF operates as a high voltage ideal diode controller by controlling the gate voltages of external N-channel and P-channel MOSFETs. It ensures that only one of the MOSFETs conducts current, acting as an ideal diode. The device monitors the input voltage and compares it with the undervoltage threshold. If the input voltage falls below the threshold, the undervoltage lockout feature disables the MOSFETs, preventing further operation. The fault flag output signals any fault conditions, such as overvoltage or reverse input polarity.
