Reset Circuit with Fixed Delay

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

rises above V

, the

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.

Active-low RESET output. RESET remains low for the reset timeout period

after all reset conditions are deasserted and then goes high.

Active-high RESET output. RESET remains high for the reset timeout period

after all reset conditions are deasserted and then goes low.
