The Texas Instruments LM809M3-2.63 is a 3-pin voltage supervisor designed for monitoring power supplies in microprocessor and digital systems. It provides a reset signal during power-up, power-down, and brown-out conditions.
This supervisor features an active-low, push-pull reset output and is available with multiple threshold options, including 2.63V. It offers a typical time delay of 240ms and a minimum power-on reset pulse width of 140ms. The device operates over a temperature range of -40°C to 105°C and has a low supply current of 15µA typical.
The LM809M3-2.63 is suitable for applications requiring precise monitoring of supply voltages. Its compact SOT-23 package makes it ideal for space-constrained designs. It is a superior upgrade to the MAX809 and MAX810.
Key electrical characteristics include a typical supply current of 0.015mA and a reset threshold accuracy of 5%. The reset output remains valid for VCC greater than or equal to 1V.
