The LMP7300MA is a Micropower Precision Comparator and Precision Reference with adjustable hysteresis. It is ideal specifications for precision threshold detecting. The precision 2.048V reference comes with a 0.25% maximum error. The comparator features micro-Power (35μW), low offset voltage and independent adjustable positive and negative hysteresis. Hysteresis control for the comparator is accomplished through two external pins. The HYSTP pin sets the positive hysteresis and the HYSTN pin sets the negative hysteresis. The comparator design isolates the VIN source impedance and the programmable hysteresis components. This isolation prevents any undesirable interaction allowing the IC to maintain a precise threshold voltage during level detection. The combination of low offset voltage, external hysteresis control and precision voltage reference provides an easy-to-use micro-Power precision threshold detector. The LMP7300 open collector output is ideal for mixed-voltage system designs.
