The BL712x series from Shanghai Belling Co., Ltd. are high-performance, dual-channel digital isolators designed for robust isolation in demanding applications. These devices offer a 100 Mbps data rate and a strong isolation barrier with a typical CMTI of 100 kV/s, an isolation rating of up to 3750 VRMS, and a projected lifetime of over 50 years. They operate across a wide supply voltage range (2.5 V to 5.5 V) and temperature range (40C to +125C), supporting 2.5-V to 5.5-V level translation. The BL712x series provides high electromagnetic immunity and low emissions with low power consumption, effectively preventing noise currents from damaging sensitive circuitry. Available in an 8-pin narrow SOIC package, these isolators are ideal for industrial automation, motor control, solar inverters, power supplies, and medical equipment.
