... Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not designed for continuous repetitive operation.

... Electrical and Functional Description of Blocks 5.1 Power Supply The TLE8104E is supplied by power supply line V including the gate control of the power stages. A capacitor between pins VS to GND is recommended. A RESET pin is available. When a low level is applied to this pin, the device enters sleep mode. In this case, all registers are set to their default values and the quiescent supply current is minimized ...

... The inductive output clamp is necessary to prevent destruction of the device. See The maximum allowed load inductance and current, however, are limited. Figure 6 Inductive Output Clamp Maximum Load Inductance During demagnetization of inductive loads, energy has to be dissipated in the TLE8104E. This energy can be calculated with following equation ...

... Over Load Protection The TLE8104E is protected in case of over load or short circuit of the load. The current is limited to I time t , the corresponding over load flag CLn is set. The channel may shut down due to over temperature. d(fault) The over load flag (CLn) of the affected channel is cleared by the rising edge of the CS signal after a successful SPI transmission ...

... The short to ground monitor information of channel n is registered in the diagnosis flag SGn The diagnosis information of the TLE8104E can either be accessed by the SPI interface or FAULT pin. With the exception of over temperature, a fault is only recognized if it lasts longer than the fault delay time t using the SPI interface and fault pin, diagnosis flags are latched in the diagnosis register of the SPI interface ...

... SPI Signal Description CS - Chip Select: The system micro controller selects the TLE8104E by means of the CS pin. Whenever the pin is in low state, data transfer can take place. When high state, any signals at the SCLK and SI pins are ignored and SO is forced into a high impedance state. ...

... 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 three TLE8104E devices in daisy chain, three times 8 bits have to be shifted through the devices. After that, the CS line must go high (see Figure 12) ...
