TPT7720,TPT7721 2 Channel Enhanced Digital Isolator
●The TPT772x devices are high-performance, dual-channel digital isolators with 5000 V-RMS(WSOP16 packages), 3750 V-RMS(SOP8 package), isolation ratings per UL 1577. These devices are also to be certified by VDE, UL, CSA, and CQC.
●The TPT772x devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. The TPT7720 device has both channels in thesame direction while the TPT7721 device has both channels in the opposite direction. In the event of input power or signal loss, the default output is low for devices UVLO suffix F and for high devices without suffix F.
●Used in conjunction with isolated power supplies, these devices help prevent noise currents on data buses, such as RS-485, RS-232, and CAN, from damaging sensitive circuitry. Through innovative chip design and layout techniques, the electromagnetic compatibility of the TPT772x devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance.
