TCPP03 compatibility with FETs that have a low Vgs(min)

rcoleman99 · ‎2025-09-11

We are looking at using the TCPP03 and TCPP01 for a system with a dual-role power port and a sink port. We want to use this dual MOSFET with both ICs (a dual MOSFET is needed for the TCPP01 to prevent backflow): https://fscdn.rohm.com/en/products/databook/datasheet/discrete/transistor/mosfet/aw2k21ar-e.pdf

The MOSFET has a Vgs(min) of -2V. There isn't much information about the gate driver circuits in the TCPP01/TCPP03 datasheets. Does the integrated gate driver drive below 0V when turning the gate off?

Thanks

Dear Rcolemann99,

The GATE pin from the TCPP01/03 is driven between 0V and 5V.

No negative voltage is present on this pin.
