U6046B-MFPY
U6046B-MFPY Datasheet
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.

| • Delay Time Range 3.7s to 20h • RC Oscillator Determines Timing Characteristics • Relay Driver with Z-diode • Debounced Input for Toggle Switch • Two Debounced Inputs ON and OFF • Load-dump Protection • RF Interference Protected • Protection According to ISO/TR7637-1 VDE 0839 • Inputs Switched to VBatt 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. The delay time can be interrupted manually, but a retrigger function is not provided.

The integrated Z-diode 14V protects the supply voltage, VS. Therefore, the operation of the IC is possible between 6V and 16V, supplied by VBatt. However, it is possible to operate the integrated circuit with a 5V supply, but it should be free of interference voltages. In this case, pin 7 is connected to pin 8 as shown in Figure 3-2 on page 3, and the R1C1 circuit is omitted.
