The MIC833 is a micropower precision dual voltage comparator with an on-chip reference and latch. High- and low-voltage thresholds are adjusted independently, allowing for wide hysteresis. Three external resistors determine the threshold voltages. Voltage detection thresholds are accurate to 1.5%. Supply current is extremely low (1µA, typical), making it ideal for portable applications. The MIC833 is supplied in Micrel's IttyBitty™ 5-lead SOT-23 package.
