LM809, LM810

SNVS052E –SEPTEMBER 1999–REVISED APRIL 2016

LM809/LM810 3-Pin Microprocessor Reset Circuits

1 Features

3 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, power-

down and brown-out conditions.

Precision Monitoring of Supply Voltages

–

Available Threshold Options:

2.63 V, 2.93 V, 3.08 V, 4.38 V, 4.63 V

•

Superior Upgrade to MAX809 and MAX810

Fully Specified Over Temperature

The function of the LM809 and LM810 are to monitor

the V_CCsupply voltage, and assert a reset signal

whenever this voltage declines below the factory-

programmed reset threshold. The reset signal

remains asserted for 240 ms after V_CCrises above

the threshold. The LM809 has an active-low RESET

output, while the LM810 has an active-high RESET

output.

140-ms Minimum Power-On Reset Pulse Width,

240-ms Typical

–

Active-Low RESET Output (LM809)

Active-High RESET Output (LM810)

•

Ensured RESET Output Valid for V_CC≥ 1 V

Low Supply Current, 15-µA Typical

Power Supply Transient Immunity

Seven standard reset voltage options are available,

suitable for monitoring 5-V, 3.3-V, and 3-V supply

voltages.

2 Applications

With a low supply current of only 15 µA, the LM809

and LM810 are ideal for use in portable equipment.
