Description
The EM6353 is an ultra-low current reset circuit available in a
large variety of configurations and very small packages for
maximum flexibility in all end-applications up to 125°C and
using power supplies between 1.5V and 5.5V.
This circuit monitors the supply voltage of any electronic
system, and generates the appropriate reset signal after a
fixed reset timeout period. The threshold defines the
minimum allowed voltage which guarantees the good
functionality of the system. When V
output remains active for an additional delay time. This
allows the system to stabilize before getting fully active.
The EM6353 features three output types: active-low push-
pull, active-low open-drain and active-high push-pull.
Small SC70-5L and SOT23-3L packages as well as ultra-low
supply current of 2.9µA make the EM6353 an ideal choice
for portable and battery-operated devices.
