MAX16010：Ultra-Small, Overvoltage Protection/Detection Circuits

The MAX16010–MAX16014 is a family of ultra-small, low-power, overvoltage protection circuits for high-voltage, high-transient systems such as those found in telecom, and industrial applications. These devices operateover a wide 5.5V to 72V supply voltage range, making them also suitable for other applications such as battery stacks, notebook computers, and servers. The MAX16010 and MAX16011 offer two independent comparators for monitoring both undervoltage and overvoltage conditions. These comparators offer open-drain outputs capable of handling voltages up to 72V. The MAX16010 features complementary enable inputs (EN/active-low EN), while the MAX16011 features an active-high enable input and a selectable active-high/low OUTB output. The MAX16012 offers a single comparator and an independent reference output. The reference output can be directly connected to either the inverting or noninverting input to select the comparator output logic. The MAX16013 and MAX16014 are overvoltage protection circuits that are capable of driving two p-channel MOSFETs to prevent reverse-battery and overvoltage conditions. One MOSFET (P1) eliminates the need for external diodes, thus minimizing the input voltage drop. The second MOSFET (P2) isolates the load or regulates the output voltage during an overvoltage condition. The MAX16014 keeps the MOSFET (P2) latched off until the input power is cycled. The MAX16010 and MAX16011 are available in small 8-pin TDFN packages, while the MAX16012/MAX16013/MAX16014 are available in small 6-pin TDFN packages. These devices are fully specified from -40°C to +125°C.
