MIC833YM5 TR Microchip

MIC833 Comparator and Reference with Adjustable Hysteresis Features General Description Optimized for Handheld Electronics, Cellular The MIC833 is a micropower precision dual-voltage Telephones, and Other Battery-Powered Devices comparator with an on-chip reference and latch. High-voltage and low-voltage thresholds are adjusted Inputs and Output Can Pull-Up to 6V Regardless independently, allowing for wide hysteresis. Three of Supply Voltage external resistors determine the threshold voltages. Independently Adjustable High- and Low-Voltage Voltage detection thresholds are accurate to 1.5%. Thresholds Supply current is extremely low (1 A, typical), making High 1.5% Voltage Threshold Accuracy it ideal for portable applications. Extremely Low 1 A Typical Supply Current The MIC833 is supplied in a 5-lead SOT-23 package. Immune to Brief Input Transients See the MIC2778 for applications that require an output 5-Lead SOT-23 Package delay.
