Hi E2E,
My customer would like to know the benefits/drawbacks of using the TPS25921 eFuse in place of the TPS24720. So far, for the eFuse, we have:
Pros of the eFuse:
Lower cost
Fewer parts
More control of operation (custom current sensitivity)
Cons of the eFuse:
No built-in current sensing
Can’t set current below 400mA
Efficiency can be worse (90 mOhm FET in normal operation)
Larger chip
4.5V minimum supply (okay)
Are there any other notable benefits/drawbacks we're missing? And is there a less expensive way to achieve this functionality?
Thanks,
-Sam
