Datasheet 10 Rev. 1.3, 2011-10-21 SPI Driver for Enhanced Relay Control SPIDER - TLE7243SL Input and Power Stages 5 Input and Power Stages The SPIDER - TLE7243SL is a eight channel low-side relay switch. The power stages are built by N-channel vertical power MOSFET transistors. 5.1 Power Supply The SPIDER - TLE7243SL is supplied by two power supply lines VDD and VDDA. The digital power supply line VDD is designed to be functional at a very wide voltage range. The analog power supply VDDA supports 5 V supply. There are power-on reset functions implemented for both supply lines. After start-up of the power supply, all SPI registers are reset to their default values and the device is in idle mode. Capacitors at pins VDD -GND and VDDA GND are recommended. There is a reset pin available. Low level at this pin causes all registers to be set to their default values and the quiescent supply currents are minimized. 5.1.1 Limp Home Mode The SPIDER - TLE7243SL offers the capability of driving dedicated channels during eventual fail-safe operation of the system. This limp home mode is activated by a high signal at pin LHI. In this mode, the SPI registers are reset and the input pins are directly routed to their corresponding channels OUT1 to OUT4, see Table 2 for details. OUT5 to OUT8 are turned off in limp home mode. Furthermore, the SPI is ignored and all input pin are referred to VDDA in order to ensure a defined operation mode if the digital supply or the microcontroller fail. A high signal on LHI overrides a Reset signal on RST. In case of a limp home during standby the device will therefore wake up and enter the limp home mode. After limp home operation all registers are reset and the device enters in standby mode following low logic RST state, or returns to idle (all channels OFF). Next SPI transmission will receive a TER Flag. Input controlled Output IN1 OUT1 IN2 OUT2 IN3 OUT3 IN4 OUT4 Table 2 Routing during limp home mode 5.2 Input Circuit There are four input pins available at SPIDER - TLE7243SL, which can be configured to be used for control of the output stages. The INn parameter of the SPI selects the input pin to be used. Figure 4 shows the input circuit of SPIDER - TLE7243SL. During Limp home mode a default routing is switched and the SPI commands are ignored.

The zener diode protects the input circuit against ESD pulses. After power-on reset, the device enters idle mode (all channel OFF). 5.2.1 Inductive Output Clamp When switching off inductive loads, the potential at pin OUT rises to VDS(CL) potential, because the inductance intends to continue driving the current. The voltage clamping is necessary to prevent destruction of the device, see Figure 5 for details. Nevertheless, the maximum allowed load inductance is limited.

The switching times tON and tOFF are designed equally.

Integrated protection functions are designed to prevent IC destruction under fault conditions described in this datasheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not designed for continuous repetitive operation. 6.1 Over Load Protection The SPIDER - TLE7243SL is protected in case of over load or short circuit of the load. After time tOFF(OVL), the over loaded channel n switches off and the according diagnosis flag Dn is set.The channel can be switched on after clearing the diagnosis flag. Please refer to Figure 7 for details.

The zener diode protects the input circuit against ESD pulses. After power-on reset, the device enters idle mode. 6.2 Over Temperature Protection A temperature sensor for each channel causes an overheated channel n to switch off to prevent destruction and the according diagnosis flag Dn is set. The channel can be switched on after clearing the diagnosis flag. Please refer to Chapter 7.1 for information on diagnosis features. 6.3 Reverse Polarity Protection In case of reverse polarity, the intrinsic body diode of the power transistor causes power dissipation. The reverse current through the intrinsic body diode of the power transistor has to be limited by the connected load. The VDD and VDDA supply pins must be protected against reverse polarity externally. The over temperature and over load protection is not active during reverse polarity.

There are following diagnosis flags implemented: The diagnosis information of the protective functions of channel n is latched in the diagnosis flag Dn. The open load diagnosis of channel n is latched in the diagnosis flag OLn. Both flags are cleared by programming the specific channel to Standby (STB). Failure Mode Comment Open Load or short circuit Diagnosis, when channel n is switched on: none to ground Diagnosis, when channel n is switched off: according to voltage level at the output pin, flag OLn is set after time td(OL). When the channel is in OFF there is Diagnosis active, in Standby the Diagnosis is not enabled Over Temperature When over temperature occurs, the according diagnosis flag Dn is set. If the affected channel n was active it is switched off. The diagnosis flags are latched until they have been cleared by programming the channel STB. Over Load (Short Circuit) When over load is detected at channel n, the affected channel is switched off after time tOFF(OVL) and the dedicated diagnosis flag Dn is set. The diagnosis flags are latched until they have been cleared by programming the channel STB 7.1 Diagnosis Characteristics Note: Characteristics show the deviation of parameter at given supply voltage and junction temperature.

The SPI is a full duplex synchronous serial slave interface, which uses four lines: SO, SI, SCLK and CS. Data is transferred by the lines SI and SO at the data rate given by SCLK. The falling edge of CS indicates the beginning of a data access. Data is sampled in on line SI at the falling edge of SCLK and shifted out on line SO at the rising edge of SCLK. Each access must be terminated by a rising edge of CS. A modulo 8 counter ensures that data is taken only, when a multiple of 8 bit has been transferred, while the minimum of 16 bit is also taken into consideration. Therefore the interface provides daisy chain capability even with 8 bit SPI devices.

It is reset to the default values after power-on reset. 8.1 SPI Signal Description CS - Chip Select: The system micro controller selects the SPIDER - TLE7243SL by means of the CS pin. Whenever the pin is in low state, data transfer can take place. When CS is in high state, any signals at the SCLK and SI pins are ignored and SO is forced into a high impedance state. CS High to Low transition: • • The diagnosis information is transferred into the shift register. SO changes from high impedance state to high or low state depending on the logic OR combination between the transmission error flag (TER) and the signal level at pin SI. As a result, even in daisy chain configuration, a high signal indicates a faulty transmission. The transmission error flag is set after any kind of reset, so a reset between two SPI commands is indicated. For details, please refer to Figure 9. This information stays available to the first rising edge of SCLK. TER SI SO 1 OR 0 SI SPI SO S CS SCLK S TER.emf Figure 9 Datasheet Transmission Error Flag on SO Line 19 Rev. 1.3, 2011-10-21 SPI Driver for Enhanced Relay Control SPIDER - TLE7243SL Serial Peripheral Interface (SPI) CS Low to High transition: Data from shift register is transferred into the input matrix register only, when after the falling edge of CS exactly a multiple (1, 2, 3, …) of eight SCLK signals have been detected, while the minimum valid length is of course 16 clocks for the 16 register bits of SPIDER - TLE7243SL. SCLK - Serial Clock: This input pin clocks the internal shift register. The serial input (SI) transfers data into the shift register on the falling edge of SCLK while the serial output (SO) shifts diagnostic information out on the rising edge of the serial clock. It is essential that the SCLK pin is in low state whenever chip select CS makes any transition. SI - Serial Input: Serial input data bits are shifted in at this pin, the most significant bit first. SI information is read on the falling edge of SCLK. Please refer to Section 8.3 for further information. SO - Serial Output: Data is shifted out serially at this pin, the most significant bit first. SO is in high impedance state until the CS pin goes to low state. New data will appear at the SO pin following the rising edge of SCLK. Please refer to Section 8.3 for further information. 8.2 Daisy Chain Capability The SPI of SPIDER - TLE7243SL provides daisy chain capability. In this configuration several devices are activated by the same CS signal MCS. The SI line of one device is connected with the SO line of another device (see Figure 10), which builds a chain. The ends of the chain are connected with the output and input of the master device, MO and MI respectively. The master device provides the master clock MCLK, which is connected to the SCLK line of each device in the chain. Figure 10 SO SPI SI SO SPI SCLK SI device 3 CS SCLK MI MCS MCLK SO SPI CS SI CS MO device 2 SCLK device 1 SPI_DasyChain.emf Daisy Chain Configuration In the SPI block of each device, there is one shift register where one bit from SI line is shifted in each SCLK. The bit shifted out can be seen at SO. After 16 SCLK cycles, the data transfer for one SPIDER - TLE7243SL has been finished. In single chip configuration, the CS line must go high to make the device accept the transferred data. In daisy chain configuration the data shifted out at device #1 has been shifted in to device #2. When using multiple devices in daisy chain, the number of bits must be correspond with the number of register bits. Figure 11 is showing a example with 3 SPI devices, where #1 and #3 are 16 bit SPI and #2 has a 8 bit SPI. To get a successful transmission, there have to be 2* 16 bit + 1* 8bit shifted through the devices. After that, the MCS line must go high.

The input register and the diagnosis register. The diagnosis register contains eight pairs of diagnosis flags, the input register contains the input multiplexer configuration. After power-on reset, all register bits are set to 1 and the device is in idle mode.
