... VP is connected to the battery via a reverse polarity protection diode (KL15). The VP pin may not source current under all conditions, especially after battery cut off. VDD (5V Voltage) Additional to the VS and VP MLX16303 needs a low current 5V voltage for the digital part and reference use. This voltage is named VDD. ...

... The IC gets 16bit data from the microcontroller via SPI. The bit will be interpreted as a command. The other bits are data. When a command word is sent to the MLX16303 the first bit on the data bus must be bit0 (LSB) followed by the bits 1-15. The first bit of the answer word from MLX16303 must be bit0 followed by the bits 1-15. ...

... If an error is detected the relevant channel will be switched off. After an error occurred it will be latched. The latched errors can only be reset by sending a CMD_ONOFF to the MLX16303. The ECU can read out the detected errors using the SPI interface. The error detection in MLX16303 reacts before any damaging or unreliable operation can occur. ...
