3 Description
The TPD1S514 Family consists of single-chip
protection solutions for 5-V, 9-V or 12-V USB V_BUS
lines, or other power buses. The bidirectional nFET
switch ensures safe current flow in both charging and
host mode while protecting the internal system
circuits from any over voltage condition at the
V_{BUS_CON} pin. On the V_{BUS_CON} pin, this device can
handle over voltage protection up to 30-V DC. After
the EN pin toggles low, any device in the TPD1S514
Family waits 20 ms before turning ON the nFET
through a soft start delay.
Typical application interfaces for the TPD1S514
Family are V_BUS lines in USB connectors typically
found in cell phones, tablets, eBooks, and portable
media players. The TPD1S514 Family can also be
applied to any system using an interface for a 5-V, 9-
V, or 12-V power rail.
