Basic Circuitry

The integrated circuit U6803B requires a stabilized supply voltage VS = 5 V ±5% to comply with its electrical characteristics. An external buffer capacitor of C = 100 nF is recommended. An integrated 14 V Zener diode between VS and ground protects the supply pin.

All input stages are provided with an integrated 250 kW pull-up resistor and can be directly connected to a microcontroller.

All output stages are open collectors, each capable of sinking 20 mA. Recommended external components:
• Pull-up resistor, R = 1 kW
• Capacitor to GND, C = 470 pF, see Figure 3 on page 4

Functional Description

General

ON state A low level at the input stage activates the corresponding output stage.

OFF state The internal pull-up resistor provides a high level to the input comparator and deactivates the output stage.
7 V Zener diodes between each input pin and GND are capable of ±10 mA clamping currents without crosstalk on adjacent input stages.

A total clamping current of ±30 mA should be observed with respect to the power dissipation.

Current Limitation of the Output Stages and Overtemperature Shutdown

A temperature-dependent current limitation in the range of 25 to 100 mA protects the
stages in case of a short. Additionally, the chip temperature is monitored. For TChip > 148°C, all outputs are disabled and automatically enabled with a hysteresis of TChip > 5°C.
