Ideal Diode, Reverse-Battery, and Overvoltage Protection Switch/Limiter Controllers with External MOSFETs. The MAX16914/MAX16915 low-quiescent-current overvoltage and reverse-battery protection controllers are designed for automotive and industrial systems that must tolerate high-voltage transient and fault conditions. These conditions include load dumps, voltage dips, and reversed input voltages. The controllers monitor the input voltage on the supply line and control two external pFETs to isolate the load from the fault condition. The external pFETs are turned on when the input supply exceeds 4.5V and stay on up to the programmed overvoltage threshold. During high-voltage fault conditions, the controllers regulate the output voltage to the set upper threshold voltage (MAX16915), or switch to high resistance (MAX16914) for the duration of the overvoltage transient to prevent damage to the downstream circuitry. The overvoltage event is indicated through an active-low, open-drain output, active-low OV.
