DESCRIPTION
The TPD1S414 is a single-chip solution for USB
connector’s V_BUS line protection. The bi-directional
nFET switch ensures safe current flow in both
charging and host mode while protecting the internal
system circuits from any over-voltage conditions at
the V_{BUS_CON} pin. On the V_{BUS_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.
