U6806B General Description

The U6806B has the following features including Six input comparators with Schmitt-trigger characteristic;Integrated protection cells (EMC, ESD, RF) dedicated to all input stages;Common shutdown by junction temperature momtor;Low voltage reset with hysteresis.

The U6806B hexdriver IC includes six non-inverted output stages with an open collector. Common thermal shutdown protects outputs against critical junction temperature. Each output can sink 250 mA.Parallel output operation is possible. The digital inputs have Schmitt-Trigger function with pull-up current sources to 5 V.The integrated circuit, U6806B, requires a stabilized supply voltage (VS=5 V ± 5%) to comply with its electrical characteristics. An external buffer capacitor of C=100 nF value 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-k pull-up resistor and can be directly connected to a microcontroller.All output stages are open-collector types each capable of sinking 250 mA to drive relays with a coil resistance of R=80 (see figure 2).The integrated Zener-diodes limit inductive surges,external free wheeling diodes are not necessary.

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 Vhysc=0.5 V typically.Meet all present and future national and international statutory requirements.Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment.It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs).The Montreal Protocol(1987 ) and its London Amendments(1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances.7-V Zener diodes between each input pin and GND are capable of ±10 mA clamping currents without crosstalk on adjacent input stages.
