MLX16303 Bi-directional Remote Sensor Unit Interface

This interface IC is designed for remote automotive sensors, especially between a main ECU and remote (sensor) units. It contains two identical interfaces and the main task of each interface is to supply one remote unit and to receive digital information from the same remote unit. It is also possible to send data as PWM voltage pulses to the remote unit, for.

Features

Two identical interface channels for remote sensor units Two connection modes: connection to OUTx and RETx or connection to OUTx and GND pin 16 bit Standard SPI for control and diagnosis via a microcontroller Supply voltage for each remote unit with a supply current up to 45mA Current limitation with an analog feed back loop for each channel Receive data from the remote unit by current modulation with a transmission rate of 10kHz Transmission of data to the remote unit via PWM voltage pulses Data input/output can be directly connected to a microcontroller input/output (CMOS) Low current consum.
