MAX6457–MAX6460
High-
Voltage, Low-Current
Voltage Monitors in SOT Packages
General Description
The MAX6457–MAX6460 high supply
voltage, low-power
voltage monitors operate over a 4V to 28V supply
voltage range. Each device includes a precision bandgap reference, one or two low-offset
voltage comparators, internal threshold hysteresis, power-good or reset timeout options, and one or two high-
voltage open-drain outputs. Two external resistors (three for window detection) set the trip threshold
voltages.
The MAX6457 is a single
voltage monitor for under
voltage or over
voltage detection. A logic-based clear input either latches the output for over
voltage applications or allows the device to operate in transparent mode. The MAX6458 includes two comparators (one over
voltage and one under
voltage) for window detection and a single output to indicate if the monitored input is within an adjustable
voltage window. The MAX6459 includes dual over
voltage/ under
voltage comparators with two independent comparator outputs. Use the MAX6459 as a window comparator with separate under
voltage and over
voltage outputs or as two independent, single
voltage monitors. The MAX6460 includes a single comparator and an internal reference, and can also accept an external reference. The inverting and noninverting inputs of the comparator are externally accessible to support positive or negative
voltage monitors and to configure the device for active...
