General Description

The LM809/810 microprocessor 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.

The function of the LM809/810 is to monitor the V_CC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 240ms after V_CC rises above the 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 5V, 3.3V, and 3V supply voltages.

With a low supply current of only 15µA, the LM809/810 are ideal for use in portable equipment. The LM809/LM810 are available in the 3-pin SOT23 package and in the 6-Lead LLP package.

Low Supply Current, 15µA typ.
Power supply transient immunity

Applications

Microprocessor Systems
Computers
Controllers
Intelligent Instruments
Portable/Battery-Powered Equipment
Automotive
