3 Description
The TPD4S014 is a single-chip solution for USB
charger port protection. This device offers low
capacitance transient voltage suppressor (TVS)
electrostatic discharge (ESD) clamps for the D+, D–,
and standard capacitance for the ID pin. On the V_BUS
pin, this device provides overvoltage protection (OVP)
up to 28 V DC. The overvoltage lockout feature
ensures that if there is a fault condition at the V_BUS
line, the TPD4S014 is able to isolate the V_BUS line to
protect the internal circuitry from damage. There is a
17-ms turn-on delay after V_BUS rises above the
undervoltage lockout (UVLO) threshold in order to let
the voltage stabilize before turning the nFET on. This
function acts as a de-glitch and prevents unnecessary
switching if there is any ringing on the line during
connection.
