Description

The ACE803ND

is a microprocessor (μP) supervisory circuit used to monitor the power supplies in μP

and digital systems. It provides excellent circuit reliability and low cost by eliminating external components

and adjustments when used with 5V, 3.3V, 3.0V or 2.5V powered circuits.

threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.

The ACE803ND has an open-drain output stage. The ACE803ND

’s open-drain RESET

output

Low supply current makes the ACE803ND ideal for use in portable equipment. The ACE803ND is

available in a SOT-323 and SOT23-3 package.
