产品概述
The LM809M3-4.63/NOPB is a 3-pin Microprocessor Supervisory Circuit with active-low RESET output. The 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, power-down and brownout conditions. The function of the LM809 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 240ms after VCC rises above the threshold.
- Power supply transient immunity
- Fully specified over-temperature
- Ensured RESET output valid for VCC >= 1V
- Superior upgrade to MAX809 and MAX810
- 140ms Minimum power-ON reset pulse width
- 15µA Typical low supply current
- Green product and no Sb/Br
