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 undervoltage or overvoltage detection.
A logic-based clear input either latches the output for overvoltage applications or allows the device to operate in transparent mode.
The MAX6458 includes two comparators (one overvoltage and one undervoltage) for window detection and a single output to indicate if the monitored input is within an adjustable voltage window.
The MAX6459 includes du...
