Description

The EM6325 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.

This circuit features a Manual Reset: an input that asserts

reset when pulled low (

Small SC70-5L and SOT23-5L packages as well as ultra-low

supply current of 2.9μA make the EM6325 an ideal choice

for portable and battery-operated devices.
