The LMP7300 is a combination comparator and reference with ideal specifications for
precision threshold detecting. The precision 2.048-V reference comes with a 0.25% maximum error.
The comparator features micropower (35 µW), low offset voltage (0.75-mV maximum), 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 micropower precision threshold detector.
The LMP7300 open collector output is ideal for mixed-voltage system designs. The output
voltage upper rail is unconstrained by VCC and can be pulled above
VCC to a maximum of 12 V. The LMP7300 is a member of the LMP precision
