LM809M3-3.08
Manufacturer: Texas Instruments
(16 reviews)
Description:
The LM809M3-3.08 microprocessor supervisory circuit can be used to monitor the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, powerdown and brown-out conditions. The function of the LM809M3-3.08 is to monitor the VCC supply 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 VCC rises above the threshold.
With a low supply current of only 15 µA, the LM809M3-3.08 is ideal for use in portable equipment. The LM809M3-3.08 has an active-low RESET output.
