DESCRIPTION

· The U6046B is a bipolar long-term timer designed for automotive environments.

· It automatically limits the operation time of high loads with a preset delay.

· Features a power-on-reset function to prevent unintentional operation of devices.

· Delay time can be manually interrupted; no retrigger function is available.

FEATURES

· Delay time ranges from 3.7 seconds to 20 hours, determined by an RC oscillator.

· Includes a relay driver with a Z-diode and debounced inputs for toggle, ON, and OFF switches.

· Provides load-dump and RF interference protection, compliant with ISO/TR7637-1 (VDE 0839).

· Inputs are switched to VBatt for enhanced functionality.

APPLICATIONS

· Suitable for controlling high loads in harsh automotive conditions.

· Ideal for applications requiring precise long-term timing with manual interruption capabilities.
