5 Isolation Types

With the bq7961X family of devices, TI offers several options for designing an isolation interface between stacked devices in a complete system. These include:

  1. Transformer/Galvanic/Inductive
  2. Capacitive + Choke
  3. Capacitive Only

Note that individual component properties and characteristics can affect signal integrity, robustness, and EMC performance. In the following sections, we go into detail of each isolation type and recommended component choices.
