Technical Documents

Texas Instruments LM809 series Voltage Supervisors are 3-pin voltage supervisors (reset IC) with active-low, push-pull reset for supply monitoring. They are designed to monitor the power supply voltage level and reset the system during power-up or brownout conditions. The LM809 series is available in fixed threshold voltages from 1.2 V to 5 V and adjustable threshold voltages from 1.2 V to 5 V. The LM809 series is also available in open-drain and push-pull output options.




Frequently Asked Questions

What are the similar products or Substitute Components of Texas Instruments LM809 series Voltage Supervisors

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

What is the difference between active-low and active-high RESET output?

In the case of an individual signal like RESET, changing the name slightly may indicate the active state. In the first case both inputs, and the output are “active high”, but in the second case both inputs, and the output are “active low” .
