Control is possible by input pins or via SPI. For TJ = 150°C the on-resistance of the power switches is below 500mΩ . 2 low side power switches for nominal currents up to 1.5A (power stages OUT5 and OUT6). Control is possible by input pins or via SPI. For TJ = 150°C the on-resistance of the power switches is below 1Ω . In order to increase the switching current or to reduce the power dissipation parallel connection of power stages is possible. Each of the 6 output stages is equipped with its own zener clamp, which limits the output voltage to a maximum of 60V. The outputs are provided with a current limitation set to a minimum of 1.5A resp. 3A. Each power stage is equipped with an own temperature sensor. Each output is protected by embedded protection functions5). In case of overload or shortcircuit to UBatt the current is internally limited and the corresponding bit combination is set (early warning). If this operation leads to an over-temperature condition, a second protection level (about 170°C) will change the output into a low duty cycle PWM (selective thermal shutdown with restart) to prevent critical chip temperatures. The following faults can be detected (individually for each output): - short to UBatt: (SCB/overload) can be detected when switches are - short to ground: (SCG) can be detected when switches are - open load: (OL) can be detected when switches are - over-temperature: (OT) will only be detected when switches are On state Off state Off state On state The fault conditions SCB, SCG and OL will not be stored until an integrated filtering time is expired (please note for PWM application). If, at one output, several errors occur in a sequence, always the last detected error will be stored (with filtering time). All fault conditions are encoded in two bits per switch and are stored in the corresponding SPI registers. Additionally there are two central diagnostic bits: one especially for over-temperature (latched result of an OR-operation out of the 6 signals of the temperature sensor) and one for fault occurrence at any output. A fault that has been detected and stored in the fault register must not be replaced by o.k.-state (11) unless it is read out by the RD_DIAG command sent by the microcontroller or an internal or external reset has been applied. I.e. the fault register will be cleared only by the RD_DIAG command. PRG - Program pin. PRG = High (VS): Parallel inputs Channel 1 to 6 are high active PRG = Low (GND): Parallel inputs Channel 1 to 6 are low active. If the parallel input pins are not connected (independent of high or low activity), channels 1 to 6 are switched OFF. PRG pin itself is internally pulled down when it is not connected. 5) The integrated protection functions prevent device destruction under fault conditions and may not be used in normal operation or permanently. V2.3 Page 7 2009-11-18 Data Sheet TLE 6232 GP The effect of the integrated under-voltage detection is similar to the effect of an external reset at pin Reset (except low current consumption): - locks all power switches regardless of their input signals - clears the fault registers - resets SPI control register Parallel Connection of Power Stages The power stages which are connected in parallel have to be switched on and off simultaneously. In case of overload the ground current and the power dissipation are increasing. The application has to take into account that all maximum ratings are observed (e.g. operating temperature TJ and total ground current IGND, see Maximal Ratings). The maximum current limitation value (or overload detection threshold) of the parallel connected power stages is the summation of the corresponding maximum values of the power stages (IOUT(lim)x + IOUT(lim)y + ....).

TLE 6232 GP always works in slave mode whereas the microcontroller provides the master function. The maximum baud rate is 5MBaud. Applying a chip select signal at CS and setting bit 7 and bit 6 of the instruction byte to „1“ and „0“ TLE 6232 GP is selected by the SPI master. SI is the data input (Signal In), SO the data output (Signal Out). Via SCLK (Serial Clock Input) the SPI clock is given by the master. V2.3 Page 8 2009-11-18 Data Sheet TLE 6232 GP SPI Signal Description CS - Chip Select. The system microcontroller selects the TLE 6232 GP by means of the CS pin. Whenever the pin is in a logic low state, data can be transferred from the µC and vice versa. CS High to Low transition: - diagnostic status information is transferred from the power outputs into the shift register. - serial input data can be clocked in from then on - SO changes from high impedance state to logic high or low state corresponding to the SO bits CS Low to High transition: - transfer of SI bits from shift register into output buffers - reset of diagnosis register To avoid any false clocking the serial clock input pin SCLK should be logic low 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. SCLK - Serial Clock. The system clock pin clocks the internal shift register of the TLE 6232 GP. The serial input (SI) accepts data into the input shift register on the falling edge of SCLK while the serial output (SO) shifts diagnostic information out of the shift register on the rising edge of serial clock. It is essential that the SCLK pin is in a logic low 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 16 clock pulses were counted during CS is active. SI - Serial Input. Serial data bits are shifted in at this pin, the most significant bit first. SI information is read in on the falling edge of SCLK. Input data is latched in the shift register and then transferred to the control buffer of the output stages. The input data consists of two bytes - a "control byte” followed by a "data byte". The control byte contains the information as to whether the data byte will be accepted or ignored (see diagnostics section). The data byte contains the input information for the six channels. A logic high level at this pin (within the data byte) will switch on the power switch, provided that the corresponding parallel input is also switched on (AND-operation for channel 1 to 6). SO - Serial Output. Diagnostic data bits are shifted out serially at this pin, the most significant bit first. SO is in a high impedance state until the CS pin goes to a logic low state. New diagnostic data will appear at the SO pin following the rising edge of SCLK. RESET - Reset pin. If the reset pin is in a logic low state, it clears the SPI shift register and switches all outputs OFF. An internal pull-up structure is provided on chip. In case of inactive chip select signal (High) or bit 7 and bit 6 of the instruction byte differing from1“ and „0“ the data output SO remains into tri-state. V2.3 Page 9 2009-11-18 Data Sheet TLE 6232 GP SPI Interface Power Stages 1...6 Power Stages 1...6 SCON_REG MUX_REG CS SCLK CS SCK SI SO SPI Control: State Machine Clock Counter Control Bits Parity Generator Shift Register DIA_REG Power Stages 1...6 SPI Communication A SPI communication starts with a SPI instruction (SI control word) sent from the controller to TLE 6232 GP. Simultaneously the device sends the first SO byte back to the µC. During a writing cycle the controller sends the data after the SPI instruction, beginning with the MSB. During a reading cycle, after having received the SPI instruction, TLE 6232 GP sends the corresponding data to the controller, also starting with the MSB. The SPI Interface consists of three register: - MUX_REG: 8-bit (1 byte) length for parallel operation mode (IN1 ... IN6 enabled or not) V2.3 Page 10 2009-11-18 Data Sheet TLE 6232 GP - SCON_REG: 8-bit (1 byte) length for serial control of the outputs (serial data bits) - DIAG_REG: 16-bit (2 byte) length. Contains the diagnostic information (2 bits per channel), a common over-temperature bit and a common fault bit. Registers MUX_REG and SCON_REG are writeable as well as readable from the microcontroller. The DIAG_REG can only be read from the µC. This leads to five different control bytes which are recognized by the IC. The following table shows the different modes.

A reset of all fault registers (and OT bit) the will only be done if the RD_DIAG command was clocked in. Characteristics of the SPI Interface If the slave select signal at CS is High or bit 7 and bit 6 of the instruction byte differ from „1“ and „0“, the state machine is set on default condition, i.e. the state machine expects an instruction. If the 5V-reset (RESET) is active, the SPI output SO is switched into tri-state. In order to increase the possible number of SPI participants on one and the same CS signal, bits 7 and 6 of the instruction byte are fixed as shown above. While receiving the first two bits of the instruction byte the data output SO has to be in tri-state. After having received the first two bits TLE6232 has to decide if it is addressed (bit 7 = high, bit 6 = low). In this case the remaining 6 bits of the instruction byte and the data byte are accepted and the diagnostic feedback respectively the data byte content (MUX, SCON) is sent to the microcontroller. Otherwise instruction and data bits are rejected and SO remains in tri-state. V2.3 Page 11 2009-11-18 Data Sheet TLE 6232 GP On a reading access the bit pattern of the data byte at the SPI input SI will be ignored. The first SO byte sent out simultaneously by the TLE 6232 GP always contains the common fault bit, the over-temperature bit and the diagnostic information of channels 6 and 5 (2 bits each). Depending on the SI control byte, the second SO byte contains the requested information. - Read back of SCON_REG (SCON bits 6 to 1 and two high bits) - Read back of MUX_REG (MUX information for channel 6 to 1 and two high bits) - Diagnostic information of channel 4 to 1 (2 bits per channel) On a writing access always the full diagnostic information of the 6 channels (2 bit per channel) and the over-temperature and common fault bit is performed. Invalid instruction/access: An instruction is invalid, if the following condition is fulfilled: - an unused instruction code is detected (see tables with SPI instructions). If an invalid instruction is detected, a writing access on a register of TLE6232 GP is not allowwed. In addition an access is invalid if the number of SPI clock pulses counted during active CS differs from exactly 16 clock pulses (falling edges are counted). - On a writing access the received data is only taken over into the internal registers and - the fault register is only cleared by the RD_DIAG command, if exactly 16 SPI clock pulses were counted while CS active.
