U6046B-MY 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.

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.

Functional Description

Power Supply Pin 8

For reasons of interference protection and surge immunity, the supply voltage pin 8 must be provided with an RC circuit as shown in Figure Dropper resistor, R1, limits the current in case of overvoltage, whereas C1 smooths the supply voltage at pin

Recommended values are R1 = 510Ω, C1 = 47 µF.

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.
