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.

Notes
ACE does not assume any responsibility for use as critical components in life support devices or systems
without the express written approval of the president and general counsel of ACE Electronics Co., LTD.
As sued herein:
1. Life support devices or systems are devices or systems which, (a) are intended for surgical implant
into the body, or (b) support or sustain life, and shoes failure to perform when properly used in
accordance with instructions for use provided in the labeling, can be reasonably expected to result in
a significant injury to the user.
2. A critical component is any component of a life support device or system whose failure to perform can
be reasonably expected to cause the failure of the life support device or system, or to affect its safety
or effectiveness.
