MAX6463UR30+T

产品概述

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
• Start-up time is 225µs
