Recommended eFuse device

S.Satoshi

Hi,

Please tell me the recommended eFuse device to meet following requirements.

18V input rating
Up to 3A
Constant current limit protection
No reverse current protection

Regarding #4, the customer plan to use eFuse as input current limit for the product with OTG function. So they need to output 5V from OUT to IN of eFuse. I think eFuse without reverse current protection can input 5V to OUT pin and output from IN pin. Is my understanding correct?

Hi Satoshi,

TPS259531DSG would serve the purpose here.
Regarding #4: Do they need current limit protection from OUT to IN of eFuse? If yes, please refer app note www.ti.com/.../slva948.pdf and let me know their feedback and questions.

Best Regards,

Hi Rakesh,

I appreciate for your proposition. Regarding TPS259531, does it have constant current limit? I could not find the word of "constant" but I guess that it has constant current limit because Figure 50 shows it.
