Description

The bi-polar long-term timer U6046B is designed to automatically limit the operation

time of high loads in the harsh automotive enviroment with a preset delay time. With

the power-on-reset function the timers guarantee that current consuming devices are

not operated unintentionally.

The delay time can be interrupted manually, but a retrigger function is not provided.
