Micropower Voltage Supply Supervisor (SVS)

PRODUCT DESCRIPTION
Datasheet not available online. Please contact the factory.

The CM3403 is a micropower low voltage supply supervisor designed to provide the necessary power-on reset control for microprocessors and memory applications. An internal pull-down resistor on the RESET output ensures the output remains valid under all supply conditions.

During either a cold-start power-up or a complete power-down sequence, the RESET output will remain at 0V while the VCC input voltage is between the threshold level and ground.

When the VCC input exceeds the preset threshold voltage, an internal timer is triggered and the RESET output remains active for a minimum of 140ms, at which point the output is taken inactive.

In the event of a "brown-out" condition and the VCC voltage collapses below the threshold the RESET output is immediately asserted.

Both the trigger threshold and the precision delay pulse are internally controlled eliminating the requirement for external components.

The CM3403 is housed in a 3-pin SOT23 package and is available with optional lead-free finishing.
