Ultra-Small, Over
voltage Protection/ Detection Circuits
General Description
The MAX16010–MAX16014 is a family of ultra-small, lowpower, over
voltage protection circuits for high-
voltage, high-transient systems such as those found in automotive, telecom, and industrial applications. These devices operate over 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 under
voltage and over
voltage conditions. These comparators offer opendrain outputs capable of handling
voltages up to 72V. The MAX16010 features complementary enable inputs (EN/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 over
voltage protection circuits that are capable of driving two p-channel
MOSFETs to prevent reverse-battery and over
voltage www.DataSheet4U.com 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 over
voltage condition. The MAX16014 keeps the
MOSFET (P2) latched off until the in...
