ISOFACE™ ISO1H801G Pin Configuration and Functionality 1.2 Pin Functionality VCC (Positive 5V logic supply) The VCC supplies the input interface that is galvanically isolated from the output driver stage. The input interface can be supplied with 5V. DIS (Output disable) The high-side outputs OUT0...OUT7 can be immediately switched off by means of the low active pin DIS that is an asynchronous signal. The input registers are also reset by the DIS signal.

ISOFACE™ ISO1H801G Functional Description 3 Functional Description 3.1 Introduction when solenoid loads are switched off. VON is then clamped to 47V (min.). The ISOFACE ISO1H801G includes 8 high-side power switches that are controlled by means of the integrated parallel interface. The interface is 8bit µC compatible. Furthermore a direct control mode can be selected that allows the direct control of the outputs OUT0...OUT7 by means of the inputs D0...D7 without any additional logic signal.

Reserved IN VOUT t TJ t t Figure 5 Overtemperature detection The following figures show the timing for a turn on into short circuit and a short circuit in on-state. Heating up of the chip may require several milliseconds, depending on external conditions.
ISOFACE™ ISO1H801G Functional Description Parallel Interface 3.5.2 uC Control Mode The ISO1H801G contains a parallel interface that can be directly controlled by the microcontroller output ports. The parallel interface can also be switched over to a direct control that allows direct changes of the outputs OUT0 ... OUT7 by means of the corresponding inputs D0 ... D7 without additional logic signals. To activate the parallel direct control mode pin CS and pin WR have to be connected both to GNDCC. 3.5.

ISOFACE™ ISO1H801G Electrical Characteristics 4 Electrical Characteristics Note: All voltages at pins 2 to 14 are measured with respect to ground GNDCC (pin 15). All voltages at pin 20 to pin 36 and TAB are measured with respect to ground GNDbb (pin 19). The voltage levels are valid if other ratings are not violated. The two voltage domains VCC and Vbb are internally galvanic isolated. 4.
