π220N31/π221N31: AC 3000Vrms；π220N61/π221N61: AC 5000Vrms產品下載
The π220N31/π221N31 devices arelow-power bidirectional isolators compatible with the I2C interfaceand are based on iDivider technology from 2PaiSemi. These devices have logicinput and output buffers that are separated by using a silicon dioxide (SiO2)barrier. These devices block high voltages and prevent noise currents fromentering the control side ground, avoiding circuit interference and damagingsensitive components.
The π220N31/π221N31devices are based on iDivider technology with functional, performance, size,and power consumption advantages as compared to optocouplers.
The π220N31 providestwo bidirectional channels, supporting a complete isolated I2Cinterface. The π221N31 provides one bidirectional channel and oneunidirectional channel for applica- tions where a bidirectional clock is notrequired. The π221N31 is used in applications that have a single master while the π220N31 is suitable formulti-master applications.
These devices feature independent 3.0V to 5.5V supplieson each side of the isolator. These devices operate from DC to 2MHz at ambienttemperatures of -40°C to +125°C.
