Description

General part information

LM3724 Series

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. Reset will be asserted for at least 100ms even after VCCrises above the reset threshold.

The LM3722 has an active-lowRESETpush-pull output. The LM3723 has an active-high RESET push-pull output. The LM3724 has an active-low open-drainRESEToutput.
