Overview
LM809M3-3.08/NOPB Description
Supervisory Circuits UP SUPERVISORY IC
The LM809 and LM810 microprocessors supervisory circuits can be used to monitor the power supplies inmicroprocessor and digital systems.
They provide a reset to the microprocessor during power-up, powerdown and brown-out conditions.
The function of the LM809 and LM810 are to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factoryprogrammed reset threshold.
The reset signal remains asserted for 240 ms after VCC rises abovethe threshold.
The LM809 has an active-low RESET output, while the LM810 has an active-high RESET output.Seven standard reset voltage options are available, suitable for monitoring 5-V, 3.3-V, and 3-V supply voltages.With a low supply current of only 15 µA, the LM809 and LM810 are ideal for use in portable equipment. LM809M3-3.08/NOPB
Features
• Precision Monitoring of Supply Voltages– Available Threshold Options: 2.63 V, 2.93 V, 3.08 V, 4.38 V, 4.63 V
