|iC-HF is a robust line driver for industrial 5 V control applications featuring six differential output channels. Single-ended, TTL-compatible input signals are transmitted as differential, 5 V RS-422 output signals at a rate up to 10 MHz. The push-pull driver stages typically provide 40 mA, present low saturation voltage, are current limited for reduced EMI emissions, and short-circuit-proof. iC-HF is protected against reverse polarity connection, disabling internal supply voltage and setting output channels to high impedance when reverse polarity connection is detected. It offers a power-good switch, delivering up to 60 mA, that allows extended reverse polarity protection for connected sensors. iC-HF supports Encoder Link. In this configuration input signals are directly linked to output pins. Analog signals from sensors can be accessed directly at output pins from iC-HF, allowing sensor calibration and alignment. Up to 9 channels can be configured as Encoder Link. Entering and exiting Encoder Link configuration requires no additional line. BiSS/SSI communication is supported through RS- 422 standard physical layer. iC-HF can also be included in a BiSS bus structure, and it can be configured as a bus termination node (BiSS bus loopback). iC-HF protects against undervoltage and overtemperature events. Output channels are left in high impedance upon any of these events, and an error is signaled through the open drain output NERR. NERR is short-circuit protected. Error signaling from sensor can be transferred via NERRI/NERR pins.
