High voltage, reinforced 2-channel, 2/0, digital isolator with 2000VRMS VIOWM and 14.5mm creepage

The ISO7820 is a

high-performance, dual-channel digital isolator with 8000VPK isolation

voltage. This device has reinforced isolation certifications according to VDE, CSA,

CQC, and TUV. The isolator provides 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 silicon dioxide

(SiO2) insulation barrier. ISO7820 has two forward channels and no

reverse-direction channel. If the input power or signal is lost, default

output is ’high’ for the ISO7820 and ’low’ for the ISO7820F device. Used in

conjunction with isolated power supplies, this device prevents noise currents on a

data bus or other circuits from entering the local ground and interfering with or

damaging sensitive circuitry. Through remarkable chip design and layout techniques,

electromagnetic compatibility of ISO7820 has been significantly enhanced to

ease system-level ESD, EFT, Surge and Emissions compliance. ISO7820 is available in 16-pin SOIC wide-body (DW) and extra-wide body

(DWW) packages. The DWW package option comes with enable pins which can be used

to put the respective outputs in high impedance for multi-controller driving

applications and to reduce power consumption.
