MAXIM MAX6375-MAX6380 Voltage Detectors Datasheet
The MAX6375 through MAX6380 are ultra-low-power circuits designed for monitoring battery, power-supply, and regulated system voltages. These devices contain a precision bandgap reference, comparator, and internally trimmed resistors to set specified trip threshold voltages without requiring external components.
Available in three versions with push-pull or open-drain outputs, these detectors assert an output signal when the Vcc supply voltage falls below a preset threshold ranging from 2.20V to 4.63V. With an ultra-low supply current of 500nA for certain variants and immunity to fast transients, they are ideal for portable equipment.
