ZSSC4151C Pin Descriptions 24-QFN Package

Note: Pins designated as “n.c.” (no connection) are not internally connected. VSSA can be routed using these pins.

EPAD [c]

Ground

Internal ground; connected to VSSA

[a] Internal pull-up.

[b] No connection required. Pins marked as “n.c.” are not internally connected and have no physical connection to the silicon.

[c] External ground pad on the bottom of the package. Recommendation: Connect the EPAD externally to VSSA (pin 2). Note: The EPAD has a

high-ohmic connection to the internal ground VSSA.
