The MAX6463UR30+T is an ultra low power voltage detector in 3 pin SOT-23 package. This circuit monitors battery, power supply and system voltages from +1.6V to +5.5V. This circuit includes a precision bandgap reference, a comparator and an internally trimmed resistor network that set specified trip thresholds and an internal 5% threshold hysteresis circuit. This device provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from +1.6V to +5.5V. It is used in load switching/power sequencing and noise-immune μP reset circuits.
Supply voltage range is 1V to 6V at TA = 0°C to +125°C
Operating temperature range from -40°C to 125°C
Propagation delay of 17μs (VCC falling at 10mV/μs)
Active-low, open-drain reset type with lower trip threshold voltage of 3V at TA = +25°C
Threshold accuracy over temperature is ±2.5%
Immune to short voltage transients
No external components
Supply current is 1μA at VCC = 5V, TA = -40°C to +85°C
