MAX6457MAX6460 High-Voltage, Low-Current Voltage Monitors in SOT Packages General Description Benefits and Features The MAX6457MAX6460 high supply voltage, low-power Wide Supply Voltage Range, 4V to 28V voltage monitors operate over a 4V to 28V supply voltage Internal 2.25V 2.5% Reference range. Each device includes a precision bandgap reference, Low Current (3.5A, typ at 12V) one or two low-offset voltage comparators, internal threshold Open-Drain n-Channel Output (28V Compliant) hysteresis, power-good or reset timeout options, and one Internal Threshold Hysteresis Options or two high-voltage open-drain outputs. Two external (0.5%, 5%, 8.3%) resistors (three for window detection) set the trip threshold Two IN-to-OUT Timeout Period Options voltages.

A logic-based clear input either latches the output for overvoltage applications or allows Immune to Short Voltage Transients the device to operate in transparent mode. The MAX6458 Small SOT23 Packages includes two comparators (one overvoltage and one Few External Components undervoltage) for window detection and a single output Fully Specified from -40C to +125C to indicate if the monitored input is within an adjustable AEC-Q100 Qualified (MAX6459UTA/V+ only) voltage window.
