DRIVENBY Basic iO-link transceiver E981.10 Features General Description Supply voltage range 8V to 36V This IC is intended to be used as transceiver in IO-Link Integrated 5V voltage regulator and standard IO mode applications in sensor and ac- Wake-up detection tuator devices. Communication and power supply work Driver capability up to 200mA across a common three wire cable to the IO-Link Mas- C/Q reverse polarity protection ter, so continued use of available wiring is possible. 3.3V / 5V compatible digital interface Baud rate selection up to 230kBaud The integrated voltage regulator provides 5V/20mA Load current monitor and over current protection for external purposes. The output driver provides up Over temperature protection to 200mA and features reverse polarity protection plus Junction temperature up to +150C over current protection. It can be congfi ured as low side, QFN20L4 package high side, or push-pull driver. The switchable slew rate allows low and optimized electromagnetic radiation. applications The tiny package outline allows usage even in applica- IO-Link is a point-to-point interface between exist- tions with very limited board space. ing efi ld busses and sensor/actuator devices. IO-Link serves the transmission of specic fi parameters or data, like diagnosis information.
