Six channels, 5000 Vrms — the isolator that bridges voltage domains without a level shifter
The TI ISO7762DW is a six-channel, unidirectional digital isolator from the ISO776x family, built with capacitive coupling technology. It delivers 5000 Vrms of galvanic isolation across the barrier, enough to meet reinforced insulation requirements in medical, industrial, and grid-tied equipment.
100 Mbps and 85 kV/µs CMTI — what the timing numbers mean for the system
At 100 Mbps, the ISO7762DW handles SPI clock rates up to 50 MHz (half-duplex) and CAN FD data phases without timing pressure. The 16 ns maximum propagation delay (tpLH / tpHL) and 4.9 ns pulse-width distortion keep the signal integrity tight enough for most sensor and control links. The 85 kV/µs common-mode transient immunity is the spec that matters in motor drives and inverters: fast-switching SiC or GaN edges can couple several kV/µs across the isolation barrier, and this part rides through those transients without corrupting the data.
Temperature range and package — where this part goes on the board
Supply decoupling should follow the layout guidelines in the datasheet — 0.1 µF and 1 µF caps close to each supply pin, with a solid ground plane under the part to maintain the isolation barrier's creepage distance.
