ACE Technology ACE809
The ACE809 microprocessor supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems. They provide s reset to the microprocessor during power-up, power-down and brown-out conditions. The function of the ACE809 is to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold.| Part No. | ACE809 |

DESCRIPTION
3-Pin Microprocessor Reset Circuits The reset signal remains asserted for 240ms after VCC rises above the threshold. The ACE809 has an active-low RESET output. The output of the ACE809 is guaranteed valid down to VCC =1V. The device is available in a SOT-23-3L package. The ACE809 is optimized to reject fast transient glitches on the VCC line. Low supply current of 25µA, (VCC=3.3V) makes these devices suitable for battery powered applications.FEATURES
