The two bidirectional channels (SDA and SCL) support a complete isolated I2C interface without the need to split bidirectional signals into separate transmit and receive paths for optocouplers. The hot-swap circuitry prevents data glitches when an unpowered card is inserted onto an active I2C bus. The iCoupler magnetic isolation technology eliminates optocoupler limitations, providing better reliability, longer life, higher speed, and lower power consumption. The 1Mbps data rate supports fast-mode I2C and SMBus\/PMBus protocols. The 30mA sink current capability on Side 2 handles heavily loaded I2C buses. The device operates from 3.0V to 5.5V on each side independently. Safety certifications include UL 1577, CSA, VDE, and IEC 60950-1\/60601-1.","working_principle":"The ADUM2250 uses ADIs iCoupler technology, where each isolation channel consists of a microscale on-chip transformer fabricated in planar IC process. The I2C bidirectional signals are internally split into two unidirectional paths communicating in opposite directions through dedicated transformer-isolated channels. A special input buffer differentiates between externally generated input signals and the devices own output signals, preventing bus contention and latch-up. When the device detects an externally driven logic low on Side 1, it transmits this to Side 2 which pulls the corresponding pin low. The input threshold is at least 50mV below the output low level, guaranteeing that the devices own output is never interpreted as an input. The hot-swap circuit suppresses glitches during live insertion by disabling outputs until VDD reaches the UVLO threshold. The 5000Vrms isolation rating is achieved through thick polyimide insulation between the transformer windings.","pin_description":"
