EM6352
Voltage Detector, High-Precision
www.DataSheet4U.com
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 VDD stays above the threshold voltage,
the output stays inactive. If VDD drops below VTH, the output
goes active. The output is guaranteed to be in the correct
state for VDD 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.

1) Top marking is the standard from 2006. No bottom marking exists. Where ## refers to the lot number (EM internal
reference only)
2) Top marking with 4 characters is standard from 2003. For lead-free/green mold (RoHS) parts, the first letter of top
marking with 4 characters begins with letter “B” instead of letter “A”. Bottom marking indicates the lot number.
