The TPT772x devices are high performance, dual channel enhanced digital isolators with 5000 VRMS (WSOP8, WSOP16), 3750 VRMS (SOP8) isolation ratings per UL 1577. These devices are also to be certified by VDE, UL, CSA, TUV, CQC and CB. The TPT772x devices provide high reliability and high performance at low power consumption while isolating digital input and output. Each isolation signal channel is separated by a double capacitive silicon dioxide insulation barrier. The TPT7720 device has both channels in the same direction while the TPT7721 and TPT7722 device has both channels in the opposite direction. In the event of input power or signal loss, the fail-safe default output is low for devices with suffix F and high for devices without suffix F. The common mode transient immunity (CMTI) and electromagnetic compatibility of the TPT772x devices have been significantly enhanced through innovative circuit design and optimized structure. TPT772x family is available in SOP8, WSOP8 and WSOP16 packages, and is characterized from −40°C to +125°C. Devices with -S suffix are qualified for Automotive Applications with AEC-Q100 Reliability Test.
