LM810 - 3-Pin Microprocessor Reset Circuits

Download the LM810 datasheet PDF. This datasheet also covers the LM809 variant, as both devices belong to the same 3-pin microprocessor reset circuits family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM809 and LM810 microprocessors supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems.

They provide a reset to the microprocessor during power-up, powerdown and brown-out conditions.
