FUNCTIONAL DESCRIPTION The L9613B is a monolithic bus driver designed to provide bidirectional serial communication in automotive applications. The device provides a bidirectional link, called K, to the VBat related diagnosis bus. It also includes a separate comparator L which is also able to be linked to the VBat bus. The input TX and output RX of K are related to VCC with her integrated pull up resistances. Also the L comparator output LO has a pull up resistance connected to VCC. All VBat bus defined inputs LI and K have supply voltage dependent thresholds together with sufficent hysteresis to suppress line spikes. These pins are protected against overvoltages, shorts to GND and VS and can also be driven beyond VS and GND. These features are also given for TX, RX and LI only taking into account the behaviour of the internal pull up resistances. The thermal shut down function switches OFF the K output if the chip temperature increases above the thermal shut down threshold. To reactivate K again the chip temperature must decrease below the K switch ON temp. To achieve no fault for VS undervoltage conditions the outputs will be switched OFF and stay at high impedance. The device is also protected against reverse battery condition. During lack of VS or GND all pins shows high impedance characteristic. To realize a lack of the VS related bus line LI and K the outputs LO and RX shows defined ON status. Supressing all 4 classes of "Schaffner" signals (Schaffner 1; 2; 3a,b; 4) all pins can be load with short energy pulses of max. 0.2mJ. All these features together with a high possible baud rate >130Kbaud, controlled output slopes for low EMI, a wide power supply voltage range and a real standby function with zero power consumption ISSB typ 1A during system depowering VCC 0.5V make this device high efficient for automotive bus system. After wake up of the system from SB condition the first output signal will have an additional delay time tdtyp 5s. The typical output voltage behaviour for the K, LO, RX outputs as a function of the output current is shown in Fig.5. Fig.6 shows a waveform of the output signal when the low level changes from RON IOUT to IOUT 2 RON + UBE state. This variation occurs due to too low output current or after a negative transient forced to the output or to the supply voltage line.

ESD application hints To improve the ESD robustness of this device above specified 2KV/HBM external blocking capacitors must be used. Nevertheless the max. energy which can be clamped by this device should not exceeds 0.2mJ for each pin. An equivalent input diagram for calculation can be seen in fig. 9.
