ACE809
Technology
3-Pin Microprocessor Reset Circuits
Description
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. 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
• Precision Vcc Monitor for 3.0V,3.3V and 5.0V Supplies
• 140ms Guaranteed Minimum RESET Output Duration
• RESET Output Guaranteed to Vcc=1.0V
• Low 25μA Supply Current.
• Vcc Transient Immunity.
• No External Components.
Application
• Embedded systems
• Computers
• Critical μP Power Supply Monitoring
• Battery Powered equipment
