Product Details

ISO1042BQDWVRQ1 is the basic-isolation, automotive ISO1042-Q1 CAN FD transceiver in an eight-pin DWV SOIC package, with the B code distinguishing it from the reinforced option.

Its silicon-dioxide isolation barrier separates the local controller ground from the bus-side ground while CAN FD communication reaches 5 Mbps, a useful boundary for battery and inverter control networks.

The ±70-V DC bus-fault tolerance and ±30-V receiver common-mode range allow the interface to withstand wiring faults and ground shifts that can occur in a vehicle harness.

The logic side accepts 1.71 to 5.5 V while the bus side needs 4.5 to 5.5 V, so both isolated supplies must be planned explicitly.

TI specifies 5000 V RMS withstand for one minute but only a 6000-V-peak surge level for this basic B variant; procurement must not substitute the reinforced rating.
