Other Parts Discussed in Thread: PMP9563, TPS23754
Hi,
I have a question about the PMOS spec.
Ineed to add 2nd source to replace original PMOS which is FDMC2523P.
The Vgs of MOS is 30V. Could we decrease to 20V ?
Our circuit refer to the PMP9563 circuit of TPS23754.
I measured the Vc voltage is about 15V with 56V POE and Vgate peak to peak is 16-17V.
I also checked the TPS23754EVM which is used SI2325DS and the Vgs is 20V.
Our desige is POE to 12V. Please help suggest if the Vgs 20V is safe to use.
