Description The triple driver IC includes three non-inverted and current-limited output stages with an open collector. Common thermal shutdown protects the outputs against critical junction temperatures. Each output can sink a current of 20 mA, parallel output operation is possible. The digital inputs have Schmitt-trigger function with pull-up resistors to 5 V. Figure 1-1.

Basic Circuitry The integrated circuit U6803B requires a stabilized supply voltage (VS = 5V ±5%) to comply with its electrical characteristics. An external buffer capacitor of C = 100 nF is recommended. An integrated 14V Zener diode between VS and ground protects the supply pin. All input stages are provided with an integrated 250 kΩ 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 kΩ • Capacitor to GND, C = 470 pF, see Figure 4-1 on page 3 2 U6803B 4762B–AUTO–09/05 U6803B 4. Functional Description 4.1 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. 7V 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. 4.2 Current Limitation of the Output Stages and Overtemperature Shutdown A temperature-dependent current limitation in the range of 25 mA 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. 4.3 Transients and Load Dump An integrated 28V Zener diode protects each output stage against transients and load-dump (Schaffner pulses). With the help of an external 1 kΩ resistor, the output transistor is capable of handling the corresponding current which flows during each of these conditions. Apart from that, the outputs are short-circuit and overload protected. 4.4 Low-voltage Detection When the supply voltage is switched on, a power-on reset pulse is generated internally which disables all output stages until a defined supply-voltage level is reached. The low-voltage detection is provided with a hysteresis of Vhyst = 0.5V typically. Figure 4-1.
