... Inputs Switched to V Batt 1. Description The bi-polar long-term timer U6046B is designed to automatically limit the operation time of high loads in the harsh automotive environment with a preset delay time. With the power-on-reset function the timers guarantee that current consuming devices are not operated unintentionally. ...
