Ultra-Low-Power Voltage Detectors and µP Supervisory Circuits
Description
The MAX6461-MAX6466 family of ultra-low-power voltage detectors and µP reset supervisory circuits monitors battery, power-supply, and system voltages. Each circuit includes a precision bandgap reference, a comparator, internally trimmed resistor networks that set specified trip thresholds, and an internal 5% threshold hysteresis circuit (see the Functional Diagram ). Output is asserted when VCC falls below the internal VTH - and remains asserted until VCC rises above VTH + (VTH + = VTH - x 1.05). These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from +1.6V to +5.5V. The MAX6461/MAX6462/MAX6463 are voltage detectors with a propagation delay of 17µs.
