EM6352

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

stays above the threshold voltage,

the output stays inactive. If V

drops below V

, the output

goes active. The output is guaranteed to be in the correct

state for V

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 SOT23 package as well as ultra-low supply current of

2.7μA makes the EM6352 an ideal choice for portable and

battery-operated devices.
