I have built an H-Bridge driver using discrete BJTs only (no driver IC). The driver gives a pretty clean simulation output. However, BJTs as we know have lower surge handling capability as compared to MOSFETS.
The BJTs that I am thinking to use are rated 1A continuous and 2A peak current with a turn-off delay of 17nS. (Priced 0.1$ @ 100 units)
MOSFETs with similar pulse capability with a delay of 11nS are available for 0.05$.
Now, my question is, can the BJTs be replaced by MOSFETs without causing reliability issues?
The high side circuit is attached below.
