Voltage Detector, High-Precision
Description
The EM6352 is an ultra-low current voltage detector
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 without a
delay time. The threshold defines the minimum allowed
voltage which guarantees the good functionality of the
system. As long as V
DD
stays above the threshold voltage,
the output stays inactive. If V
DD
drops below V
TH
, the output
goes active. The output is guaranteed to be in the correct
state for V
DD
down to 0.8V. There are 12 reset threshold
voltages starting as low as 1.31V and up to 4.63V. The
EM6352 features three output types: active-low push-pull,
active-low open-drain and active-high push-pull.
Small SC70 and SOT23 packages as well as ultra-low
supply current of 2.7μA make the EM6352 an ideal choice
for portable and battery-operated devices.
