CMT810X

The (CMT8100,CMT8101) devices are high reliability bidirectional isolators that are compatible with I2C interface. The CMT810x devices are AEC-Q100 qualified. The CMT810x devices are safety certified by UL1577 supporting several insulation withstand voltages (3.75 kVrms, 5 kVrms), while providing high electromagnetic immunity and low emissions at low power consumption. The I2C clock of the CMT810x is up to 2 MHz, and the common-mode transient immunity (CMTI) is up to 150 kV/us. Wide supply voltage of the CMT810x devices supports to connect with most digital interfaces directly, easy to do the level shift. High system level EMC performance enhances device reliability and stability.FeaturesUp to 5000 Vrms insulation voltageI2C Clock rate: up to 2 MHzPower supply voltage: 2.5 V to 5.5 VAEC-Q100 Grade 1 qualifiedHigh CMTI: 150 kV/usChip level ESD: HBM: ±6 kVHigh system level EMC performance:• Enhanced system level ESD, EFT, surge immunityIsolation barrier life: > 60 yearsLow power consumption: 1.5mA/ch (1 Mbps)Low propagation delay: <15 nsOperation temperature: -40℃~125℃RoHS-compliant packages:• SOIC-8 narrow body• SOIC-16 wide bodySafety regulatory approvals• UL recognition: up to 5000 Vrms for 1 minute per UL1577• CQC certification per GB4943.1-2011• CSA component notice 5A• DIN VDE V 0884-11:2017-01ApplicationsPower over EthernetIsolated I2C, SMBus, or PMBus interfaceI2C level shiftingBattery management
