The LM809M3-4.63 from Texas Instruments is a 3-pin voltage supervisor IC used for monitoring power supply voltages in microprocessor and digital systems. It asserts a reset signal during power-up, power-down, and brown-out conditions, ensuring system stability.
This supervisor monitors a single supply voltage and features a typical threshold voltage of 4.63V with an accuracy of 5%. The reset output is active-low and push-pull, with a typical time delay of 240ms and a minimum power-on reset pulse width of 140ms. It operates over a temperature range of -40°C to 105°C and has a low typical supply current of 0.015mA.
The LM809M3-4.63 is available in a SOT-23-3 package, suitable for surface mounting. It is designed as a superior upgrade to MAX809 and MAX810 devices, offering precision monitoring and power supply transient immunity.
