MIC833

MIC833 Micrel MIC833 Comparator and Reference with Adj. Hystersis Advance Information General Description 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%. Supply current is extremely low (1µA, typical), making it ideal for portable applications. The MIC833 is supplied in Micrel’s IttyBitty™ 5-lead SOT-235 package. See the MIC2778 for applications requiring an output delay. Features Optimized for PDAs, cellular telephones, pagers, and other battery-powered devices Inputs and output can pulled up to 6V regardless of supply voltage Independently adjustable high- and low-voltage thresholds High ±1% voltage threshold accuracy Extremely low 1µA typical supply current Immune to brief input transients 5-lead SOT-23 package Applications PDAs Pagers Cordless phones Consumer electronics Embedded controllers Personal electronics Ordering Information Part Number MIC833BM5 Marking B11 Accuracy 1% Temperature Range –40°C to +85°C Package SOT-23-5 Typical Application VIN VDD MIC833 R1 5 3 VPULL-UP 4 RPU VOUT VLTH > VHTH VREF = 1.24V VLTH(max) = VHTH(max) = 6V VPULL-UP(max) = 6V 1.5V ≤ VDD ≤ 5.5V VDD LTH HTH OUT GND R2 1 2 R3 IttyBitty™ is a trademark of Micrel, Inc.
