The SPI interface provides daisy chain capability. The SPIDER - TLE 7240SL is equipped with four input pins that can be individually routed to the output control of their dedicated channels thus offering flexibility in design and PCB layout. The input multiplexer is controlled via SPI. There is a dedicated limp home pin LHI which provides a straightforward usage of the input pins as dedicated driver for four outputs. The device provides full diagnosis of the load, which is open load as well as short circuit detection. The SPI diagnosis bits indicate latched fault conditions that may have occurred. Each output stage is protected against short circuit. In case of over load, the affected channel switches off. There are temperature sensors available for each channel to protect the device in case of over temperature. The device is supplied by two power supply lines. The analog supply supports 5 V, the digital supply offers a very wide flexibility in supply voltage ranging from V up to V. The power transistors are built by N-channel vertical power MOSFETs. The inputs are ground referenced CMOS compatible. The device is monolithically integrated in Smart Power Technology. In terms of PCB layout improvement, all output pins are available at one side of the device. The other side bundles the signals to the micro-controller.
