MAX6462
Ultra-Low-Power Voltage Detectors and µP Supervisory Circuits
Part Details
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.
The MAX6464/MAX6465/MAX6466 are µP supervisory circuits with a minimum reset timeout period of 150ms. All devices are available with thresholds from +1.6V to +5.5V in 100mV increments.
The family is available with three output stage options: push-pull with active-low output, push-pull with active-high output, and open drain with active-low output. These devices are available in SC70 and SOT23 packages specified over the -40°C to +125°C temperature range.
