Figure 12: Comparison of integrated isolation to optocoupler
For applications requiring only half-insulation, the BM60212FV-C can be used, as shown in Figure 11.
The high-side devices are inductively isolated, while the low-side devices are driven directly from
the control-voltage reference. This reduces design complexity and cost while providing a safe and
effective means of switching control.
When comparing Rohm’s inductively coupled gate drivers to the more commonplace optical
isolation, significant performance benefits can be gained. As shown in Figure 12, the turn-on and
turn-off times of the inductive drivers are more than twice as fast, even at elevated operating
temperatures.
