LM3723 - 5-Pin Microprocessor Reset Circuits

Download the LM3723 datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same 5-pin microprocessor reset circuits family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM3722/LM3723/LM3724 microprocessor supervisory circuits monitor the power supplies in microprocessor and digital systems.

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

Key Features

LM3722/LM3723/LM3724 5-Pin Microprocessor Reset Circuits June 2001 LM3722/LM3723/LM3724 5-Pin Microprocessor Reset Circuits General Description The LM3722/LM3723/LM3724 microprocessor supervisory circuits monitor the power supplies in microprocessor and digital systems. They provide a reset to the microprocessor during power-up, power-down, brown-out conditions, and manual reset. The LM3722/LM3723/LM3724 asserts a reset signal whenever the supply decreases below the factory-programmed reset threshold for at least 100 ms. The reset signal remains asserted for 190 ms after VCC rises above the threshold. The LM3722 has an active-low RESET push-pull output. The LM3723 has an active-high RESET push-pull output. The LM3724 has an active-low open-drain RESET output.
