6 / 23 page  Datasheet 6 Revision 2.4, 2014-10-20 ISOFACE™ ISO1H816G Pin Configuration and Functionality 1.2 Pin Functionality VCC (Positive 3.3/5V logic supply) The VCC supplies the input interface that is galvanically isolated from the output driver stage. The input interface can be supplied with 3.3V / 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. The output remains switched off after low-high transient of DIS, till new data is written into the input interface. Current Sink to GNDCC CS (Chip select) The system microcontroller selects the ISO1H816G by means of the low active pin CS to activate the interface. Current Source to VCC SCLK (Serial shift clock) SCLK (serial clock) is used to synchronize the data transfer between the master and the ISO1H816G. Data present at the SI pin are latched on the rising edge of the serial clock input, while data at the SO pin is updated after the falling edge of SCLK. Current Source to VCC SI (Serial data input) This pin is used to transfer data into the device. Data is latched on the rising edge of the serial clock. Current Sink to GNDCC SO (Serial data output) SO can be connected to a serial input of a further IC to build a daisy-chain configuration. It is only actvated if CS is in low state, otherwise this output is in high impedance state. DIAG (Common diagnostic output) The low active DIAG signal contains the OR-wired information of the separated overtemperature detection units for each channel.The output pin DIAG provides an open drain functionality. A current source is also connected to the pin DIAG. In normal operation the signal DIAG is high. When overtemperature or Vbb below ON-Limit is detected the signal DIAG changes to low. GNDCC (Ground for VCC domain) This pin acts as the ground reference for the input interface that is supplied by VCC. GNDbb (Output driver ground domain) This pin acts as the ground reference for the output driver that is supplied by Vbb. OUT0 ... OUT7 (High side output channel 0 ... 7) The output high side channels are internally connected to Vbb and controlled by the corresponding data input. TAB (Vbb, Positive supply for output driver) The heatslug is connected to the positive supply port of the output interface. |
