U6046B Rear Window Heating Long-term Timer IC

Description

The bipolar long-term timer LD6046 (analog 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.

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