The Texas Instruments LM809M3-3.08 is a 3-pin voltage supervisor IC that monitors a single power supply voltage. It asserts a reset signal when the supply voltage drops below a factory-programmed threshold, ensuring system stability during power-up, power-down, and brown-out conditions.
Key electrical specifications include a typical quiescent current of 0.015mA and a reset threshold accuracy of 5%. The reset output is active-low and push-pull, with a typical time delay of 240ms. The device is available with multiple threshold options, including 3.08V for this specific part number.
This supervisor IC is housed in a compact SOT-23-3 surface-mount package, making it suitable for space-constrained applications. It operates over a temperature range of -40°C to 105°C.
The LM809M3-3.08 is designed for ease of use and offers superior performance as an upgrade to older supervisor ICs. Its robust design ensures the reset output remains valid for VCC down to 1V.
