The H-Bridge is protected against over-temperature and short circuits and has an under voltage lockout for all the supply voltages “VS” (main DC power supply). All malfunctions cause the output stages to go tristate. The device is configurable by the DMS pin. When grounded, the device gives diagnostic information via a simple error flag. When supplied with VCC = 5 V, the device works in SPI mode. In this mode, detailed failure diagnosis is available via the serial interface.

The outputs OUT1 and OUT2 are set to High or Low by the parallel inputs IN1 and IN2, respectively. In addition, the outputs can be disabled (set to tristate) by the Disable and Enable inputs DIS and EN. Inputs IN1, IN2 and DIS have an internal pull-up. Input EN has an internal pull-down.

Integrated circuits protect the outputs against over current and over-temperature if there is a short-circuit to ground, to the supply voltage or across the load. Positive and negative voltage spikes, which occur when switching inductive loads, are limited by integrated freewheeling diodes. To drive the gates of the high-side DMOS, an internal charge pump is integrated to generate a voltage higher than the supply voltage. 2.2.1 Chopper Current Limitation To limit the output current at low power loss, a chopper current limitation is integrated as shown in Figure 3. The current is measured by sense cells integrated in the low-side switches. When the current limit IL has been exceeded for a time tb, all output stages are switched off for a fixed time ta. Blanking time tb IOUT Current limit IL Switch-off time ta time Figure 3 Data Sheet Chopper current limitation 6 Rev. 1.5, 2010-11-05 TLE 7209-2R Circuit Description 2.2.2 Temperature-depending Current Reduction For TILR < Tj < TSD the current limit IL = 2.5 A ± 1.1 A as shown in Figure 4 decreases from IL = 6.6 A ± 1.1 A to A 6.6A range of overtemperature shut-down tolerance of temperature dependent current reduction IL 2.5A Tj Figure 4 2.3 TILR TSD °C Temperature dependent current reduction Protection The TLE 7209-2R is protected against short circuits, overload and invalid supply voltage by the following measures: 2.3.1 Short circuit to Ground The high-side switches are protected against a short of the output to ground by an over current shut-down. If a high-side switch is turned on and the current rises above the short circuit detection current IOUK all output transistors are turned off after a typical filter time of 2 μs, and the error bit “Short Circuit to Ground on output 1 (2)”, SCG1 (SCG2) is stored in the internal status register. 2.3.2 Short circuit to VS Due to the chopper current regulation, the low-side switches are already protected against a short to the supply voltage. To be able to distinguish a short circuit from normal current limit operation, the current limitation is deactivated for the blanking time tb after the current has exceeded the current limit threshold IL. If the short circuit detection current IOUK is reached within this blanking time, a short circuit is detected (see Figure 5). All output transistors are turned OFF and the according error bit “Short Circuit to Battery on output 1 (2)”, SCB1 (SCB2) is set.

Right: short circuit is detected Short circuit across the load If short circuit messages from high- and low-side switch occur simultaneously within a delay time of typically 2μs, the error bit “Short Circuit Over Load”, SCOL is set. 2.3.4 Over-Temperature In case of high DC-currents, insufficient cooling or high ambient temperature, the chip temperature may rise above the thermal shut-down temperature TSD. In that case, all output transistors are shut-down and the error-bit “Over-Temperature”, OT is set. 2.3.5 Under-Voltage shut-down If the supply-voltage at the VS pins falls below the under-voltage detection threshold, the outputs are set to tristate and the error-bit “Under-Voltage at VS“ is set. 2.4 Diagnosis The Diagnosis-Mode can be selected between SPI-Diagnosis and Status-Flag Diagnosis. The choice of the Diagnosis-Mode is selected by the voltage-level on Pin 12 (DMS Diagnosis Mode Selection): • DMS = GND, Status-Flag Mode • DMS = VCC, SPI-Diagnosis Mode For the connection of Pins SDI, SDO, CSN and SCK/SF see Figure 14 and Figure 15. Data Sheet 8 Rev. 1.5, 2010-11-05 TLE 7209-2R Circuit Description 2.4.1 Status-Flag (SF) Mode (DMS = GND) 184.108.40.206 SF output In SF-mode, pin 2 is used as an open-drain output status-flag. The pin has to be pulled to the logic supply voltage with a pull-up resistor, 47 kOhm recommended. In case of any failure that leads to a shut-down of the outputs, the status-flag is set (e.g. SF pin pulled to low). These failures are: – – – – – Under Voltage on VS Short circuit of OUT1 or OUT2 against VS or GND Short circuit between OUT1 and OUT2 Over-current Over-temperature SF is also pulled low when the outputs are disabled by EN or DIS. 220.127.116.11 Fault storage and reset – In case of under-Voltage, the failure is not latched. As soon as VS falls below the under-Voltage detection threshold, the output stage switches in tristate and the statusflag is set from high level to low-level. If the voltage has risen above the specified value again, the output stage switches on again and the status-flag is reset to high-level. The Under Voltage failure is shown at the SF pin for VS in the voltage range below the detection threshold (typical 4.2V) down to 2.5V. – In the SF-mode, all internal circuitry is supplied by the voltage on VS. For that reason, a loss of VS supply voltage leads to a reset of all stored information (Power-ONReset). This Power-ON-Reset occurs as soon as under-Voltage is detected on VS – In case of short circuit, over-current or over-temperature, the fault will be stored. The output stage remains in tristate and the status-flag at low-level until the error is reset by one of the following conditions: H -> L on DIS, L -> H on EN or Power-ON Reset. 2.4.2 SPI-Mode (DMS = 5V) 18.104.22.168 SPI-Interface The serial SPI interface establishes a communication link between TLE 7209-2R and the systems microcontroller. The TLE 7209-2R always operates in slave mode whereas the controller provides the master function. The maximum baud rate is 2 MBaud (200pF on SDO). By applying an active slave select signal at CSN the TLE 7209-2R is selected by the SPI master. SDI is the data input (Slave In), SDO the data output (Slave Out). Via SCK (Serial Clock Input) the SPI clock is provided by the master. In case of inactive slave select signal (High) the data output SDO goes into tristate. Data Sheet 9 Rev. 1.5, 2010-11-05 TLE 7209-2R Circuit Description The first two bits of an instruction may be used to establish an extended deviceaddressing. This gives the opportunity to operate up to 4 Slave-devices sharing one common CSN signal from the Master-Unit (see Figure 7) S P I p o w e rs u p p ly DMS CSN S P I - C o n t r o l: SCK SDI SDO - > s t a t e m a c h in e - > c lo c k c o u n t e r - > in s t r u c t io n r e c o g n it io n s h if t - r e g is t e r 8 D IA _ R E G R eset 8 D ia g n o s t ic s D IS OR DMS U n d e rv o lt a g e EN Figure 6 22.214.171.124 SPI block-diagram Characteristics of the SPI Interface 1. When DMS is > 3.5V, the SPI is active, independently of the state of EN or DIS. During active reset conditions (DMS < 3.5V) the SPI is driven into its default state. When reset becomes inactive, the state machine enters into a wait-state for the next instruction. 2. If the slave select signal at CSN is inactive (high), the state machine is forced to enter the wait-state, i.e. the state machine waits for the following instruction. 3. During active (low) state of the select signal CSN the falling edge of the serial clock signal SCK will be used to latch the input data at SDI. Output data at SDO are driven with the rising edge of SCK (see timing diagram Figure 13) 4. Chip-address: In order to establish the option of extended addressing the uppermost two bits of the instruction-byte (i.e the first two SDI-bits of a Frame) are reserved to send a chipaddress. To avoid a bus conflict the output SDO must stay high impedance during the addressing phase of a frame (i.e. until the address-bits are recognized as valid chipaddress). If the chip-address does not match, the data at SDI will be ignored and SDO remains high impedance for the complete frame. See also Figure 7 5. Verification byte: Simultaneously to the receipt of an SPI instruction TLE 7209-2R transmits a verification byte via the output SDO to the controller. Refer to Figure 8. This byte indicates normal or abnormal operation of the SPI. It contains an initial bit pattern and a flag indicating an error occurred during the previous access. Data Sheet 10 Rev. 1.5, 2010-11-05 TLE 7209-2R Circuit Description 6. Because only read access is used in the TLE 7209-2R, the SDI data-bits (2nd byte) are not used 7. Invalid instruction/access: An instruction is invalid if an unused instruction code is detected (see tables with SPI instructions). In case an unused instruction code occurred, the data byte “ffhex” (no error) will be transmitted after having sent the verification byte. This transmission takes place within the same SPI-frame that contained the unused instruction byte. In addition any transmission is invalid if the number of SPI clock pulses (falling edge) counted during active CSN differs from exactly 16 clock pulses. If an invalid instruction is detected, bit TRANS_F in the following verification byte (next SPI transmission) is set to HIGH. The TRANS_F bit must not be cleared before it has been sent to the microcontroller. 8. Transfer error bit TRANS_F: The bit TRANS_F indicates an error during the previous transfer. An error is considered to have occurred when an invalid command was sent, the number of SPI clock pulses (falling edge) counted during active CSN was less than or greater than 16 clock pulses, or SPI clock (SCK) was logical high during falling edge of CSN.

The chip-address of the TLE 7209-2R is 00. During read-access, the output data according to the register requested in the instruction byte are applied to SDO within the same SPI frame. That means, the output data corresponding to an instruction byte sent during one SPI frame are transmitted to SDO during the same SPI frame.

In this case, errors are encoded according to the following priority list. – Priority 1: Under Voltage (please note that after removal of Under Voltage, the original error will be restored, see below) – Priority 2: Short circuit across the load – Priority 3: all other short circuits – Priority 4: open load If a failure of higher priority is detected, the failures of lower priority are no longer visible in the encoded SPI message. Fault storage and reset of the Diagnosis Register DIA_REG Register DIA_REG is reset upon the following conditions: – With the rising edge of the CSN-Signal after the SPI-instruction RD_DIA. This reset only takes place if the correct number of 16 SCK pulses has been counted. – When the voltage on DMS exceeds the threshold for detecting SPI-Mode (after Under Voltage condition). Under Voltage on Vs (typ. < 5,0V) sets Bit 0.... Bit 3 of DIA_REG to 0000. If Vs rises above the Under Voltage level, Bits of DIA_REG are restored (when DMS > 3.5V). – A rising edge on EN while DIS=0 or a falling edge on DIS while EN=1 re-activates the output power-stages, and resets the DIA_REG register.

The two numbers are read-only accessible via the SPI instructions RD_IDENT and RD_VERSION as described in Section 22.214.171.124. The device ID is defined to allow identification of different IC-Types by software and is fixed for the TLE 7209-2R. The Version number may be utilized to distinguish different states of hardware and is updated with each redesign of the TLE 7209-2R. The contents is divided into an upper 4 bit field reserved to define revisions (SWR) corresponding to specific software releases and a lower 4 bit field utilized to identify the actual mask set revision (MSR). Both (SWR and MSR) will start with 0000b and are increased by 1 every time an according modification of the hardware is introduced.
