It’s on the more pricy side of TI eFuses but the wide current range and flexibility in voltage will allow us to save costs by requiring fewer ICs if we can keep the same system working into the next-generation vehicle.
Calculated Component Values for Protection Functions (Current Limiting, Slew Rate, …)
Overcurrent Limit
According to the datasheet, the formula for determining the resistance of a particular current limit is…
