3 Description
The TPD1S414 device is a single-chip solution for a
USB connector’s VBUS line protection. The
bidirectional nFET switch ensures safe current flow in
both charging and host mode while protecting the
internal system circuits from any overvoltage
conditions at the VBUS_CON pin. On the VBUS_CON pin,
this device can handle overvoltage protection up to
30 V. After the EN pin toggles low, the TPD1S414
waits 20 ms before turning ON the nFET through a
soft-start delay. ACK pin indicates the FET is
completely turned ON.
The typical application interface for the TPD1S414 is
the VBUS line in USB connectors. Typical end
equipment for TPD1S414 are mobiles phones,
tablets, wearables, and electronic-point-of-sale
(EPOS). The TPD1S414 can also be applied to any
system using an interface with a 5-V power rail.
