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. GNDbb (Output driver ground domain) This pin acts as the ground reference for the output driver that is supplied by Vbb. 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 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. 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.

The outputs OUT0...OUT7 are controlled by the data of the serial input SI. The IC can replace 8 optocouplers and the 8 high-side switches in conventional I/O-Applications as a galvanic isolation is implemented by means of the integrated coreless transformer technology. The µC compatible interface allows a direct connection to the ports of a microcontroller without the need for other components. Each of the 8 high-side power switches is protected against short to Vbb, overload, overtemperature and against overvoltage by an active zener clamp. Each of the eight output stages has its own zener clamp that causes a voltage limitation at the power transistor when solenoid loads are switched off. VON is then clamped to 47V (min.). Vbb VON OUTx GNDbb Figure 3 Power Supply Inductive and overvoltage output clamp (each channel) Energy is stored in the load inductance during an inductive load switch-off. The IC contains 2 galvanic isolated voltage domains that are independent from each other. The input interface is supplied at VCC and the output stage is supplied at Vbb. The different voltage domains can be switched on at different time. The output stage is only enabled once the input stage enters a stable state. 3.3 EL = 1 ⁄ 2 × L × IL 2 Ebb EAS ELoad Vbb Output Stage Dx OUTx L Each channel contains a high-side vertical power FET that is protected by embedded protection functions. Vbb GNDbb RL Output Stage Control Figure 4 Each output is independently controlled by an output latch and a common reset line via the pin DIS that disables all eight outputs and resets the latches. Serial data input (SI) is read on the rising edge of the serial clock SCLK. A logic high input data bit turns the respective output channel ON, a logic low data bit turns it OFF. CS must be low whilst shifting all the serial data into the device. A low-to-high transition of CS transfers the serial data input bits to the output buffer. Datasheet EL ZL The continuous current for each channel is 1.2A (all channels ON). 3.3.1 Vbb Vz The diagnostic logic on the power chip recognizes the overtemperature information of each power transistor The information is send via the internal coreless transformer to the pin DIAG at the input interface. 3.2 Power Transistor Overvoltage Protection ER Inductive load switch-off energy dissipation (each channel) While demagnetizing the load inductance, the energy dissipation in the DMOS is E AS = E bb + E L – E R = V ON ( CL ) × i L ( t )dt with an approximate solution for RL > 0Ω:: IL × L IL × RL ⎞ E AS = ---------------- × ( V bb + V ON ( CL ) ) × ln ⎛⎝ 1 + -----------------------2 × RL V ON ( CL ) ⎠ 8 Revision 2.4, 2014-10-20 ISOFACE™ ISO1H816G Functional Description 3.3.3 Power Transistor Overcurrent Protection IN The outputs are provided with a current limitation that enters a repetitive switched mode after an initial peak current has been exceeded. The initial peak short circuit current limit is set to IL(SCp) at Tj = 125°C. During the repetitive short circuit the current limit is set to IL(SCr). If this operation leads to an overtemperature condition, a second protection level (Tj > 135°C) will change the output into a low duty cycle PWM (selective thermal shutdown with restart) to prevent critical chip temperatures. t VOUT Normal operation IL Output short to GND IL(SCp) t IL(SCr) t DIAG IN t VOUT t TJ t DIAG t Short circuit in on-state, shut down down by overtemperature, restart by cooling 3.4 Common Diagnostic Output The overtemperature detection information are ORwired in the common diagnostic output block.

Serial data bits are shifted in at this pin, the most significant bit first. SI information is read in on the rising edge of the SCLK. Input data is latched in the shift register and then transferred to the control buffer of the output stages. The ISO1H816G contains a serial interface that can be directly controlled by the microcontroller output ports. 3.5.1 SPI Signal Description SO - Serial output. SO is in a high impedance state until the CS pin goes to a logic low state. The data of the internal shift register are shifted out serially at this pin. The most significant bit will appear at first. The further bits will appear following the falling edge of SCLK. CS - Chip select. The system microcontroller selects the ISO1H816G by means of the CS pin. Whenever the pin is in a logic low state, data can be transferred from the µC. CS High to low transition: •Serial input data can be clocked in from then on 3.5.2 SPI Bus Concepts 3.5.2.1 Independent Individual Control Each IC with a SPI is controlled individually and independently by an SPI master, as in a directional point-to-point communication.The port requirements for this topology are the greatest, because for each controlled IC an individual SPI at the µC is needed (SCLK, CS, SI). All ICs can be addressed simultaneously with the full SPI bandwidth. •SO changes from high impendance state to logic high or low state corresponding to the SO bit-state CS Low to high transition: •Transfer of SI bits from shift register into output buffers, if number of clock signals was an integer multiple of 8 SPI 1 •SO changes from the SO bit-state to high impendance state CLK Tx a1 Tx a2 SCLK CS SI Output lines SO SPI - Interface IC1 To avoid any false clocking the serial input pin SCLK should be logic high state during high-to-low transition of CS. When CS is in a logic high state, any signals at the SCLK and SI pins are ignored and SO is forced into a high impedance state. The integrated modulo counter that counts the number of clocks avoids the take over of invalid commands caused by a spike on the clock line or wrong number of clock cycles. A command is only taken over, if after the low-to-high transition of the CS signal the number of counted clock cycles is recognized as a multiple of 8. SPI n SCLK CS SI Output lines SO SPI - Interface µC SCLK - Serial clock. The system clock pin clocks the internal shift register of the ISO1H816G. The serial input (SI) accepts data into the input shift register on the rising edge of SCLK while the serial output (SO) shifts the output information out of the shift register on the falling edge of the serial clock. It is essential that the SCLK pin is in a logic high state whenever chip select CS makes any transition. The number of clock pulses will be counted during a chip select cycle. The received data will only be accepted, if exactly an integer multiple of 8 clock pulses were counted during CS is active. Datasheet CLK Tx n1 Tx n2 ICn Number of adressed ICs = n Number of necessary control and data ports = 3 n Individual ICs are adressed by the chip select Figure 9 10 Individual independent control of each IC with SPI Revision 2.4, 2014-10-20 ISOFACE™ ISO1H816G Functional Description 3.5.2.2 Daisy-chain Configuration 3.6 The connection of different ICs and a µC as shown in Fig. 10 is called a daisy-chain. For this type of bustopology only one SPI interface of the µC for two or more ICs is needed. All ICs share the same clock and chip select port of the SPI master. That is all ICs are active and addressed simultaneously. The data out of the µC is connected to the SI of the first IC in the line. Each SO of an IC is connected to the SI of the next IC in the line. SPI 1 CLK Tx a1 Tx a2 SCLK CS SI SO Transmission Failure Detection There is a failure detection unit integrated to ensure also a stable functionality during the integrated coreless transformer transmission. This unit decides whether the transmitted data is valid or not. If four times serial data coming from the internal registers is not accepted the output stages are switched off until the next valid data is received. Output lines SPI - Interface IC1 SCLK CS SI Output lines SPI - Interface µC ICn Number of adressed ICs = n Number of necessary control and data ports = 3 All ICs are adressed by the common chip select Figure 10 SPI bus all ICs in a “daisy chain” configuration The µC feeds the data bits into the SI of IC1 (first IC in the chain). The bits coming from the SO of IC1 are directly shifted into the SI of the next IC. As long as the chip select is inactive (logic high) all the IC SPIs ignore the clock (SCLK) and input signals (SI) and all outputs (SO) are in tristate. As long as the chip select is active the SPI register works as a simple shift register. With each clock signal one input is shifted into the SPI register (SI), each bit in the shift register moves one position further within the register, and the last bit in the SPI shift register is shifted out of SO. This is continued as long as the chip select is active (logic low) and clock signals are applied. The data is then only taken over to the output buffers of each IC when the CS signal changes to high from low and recognized as valid data by the internal modulo counter.

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 ,GNDCC and Vbb ,GNDbb are internally galvanically isolated. 4.1 Absolute Maximum Ratings Note: Absolute maximum ratings are defined as ratings, which when being exceeded may lead to destruction of the integrated circuit. For the same reason make sure, that any capacitor that will be connected to pin 2 (VCC) and TAB (Vbb) is discharged before assembling the application circuit. Supply voltages higher than Vbb(AZ) require an external current limit for the GNDbb pin, e.g. with a 15Ω resistor in GNDbb connection. Operating at absolute maximum ratings can lead to a reduced lifetime.
