Each circuit includes a precise bandgap reference; a comparator, a reset timeout circuit, internally trimmed resistor networks that set specified trip thresholds, and an internal 5% threshold hysteresis circuit (see the Block Diagram). Output is asserted when VCC falls below the internal VTH- and remains asserted until VCC rises above VTH+ (VTH+ = VTH-×1.05) after a reset timeout period. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring normal systems voltage from +1.8V to +5V in 100mV increments. The series are voltage detectors with a propagation delay of 35µs. The family is available with four output stage options: push-pull with active-low output, push-pull with active- high output, open drain with active-low output and bidirection port with active-low output and pushbutton reset input. These devices specified over the -40°C to +85°C temperature range. Table 1.
