What is this 6 pin IC

What is the IC on the Fusion 8-Channel SPDT Relay Controller. It is a small 6 pin smd, and theres a handfull of them on the face of the board. Written on the package is 4D 20 t. And on the mechanical drawing its labeled “EN”.

No, it’s a larger chip on the board. It’s a Pic chip. I believe that 6 pin IC is part of the driver circuit for the relays.
