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 VBUS 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 VBUS line, the TPD4S014 is able to isolate the VBUS line to protect the internal circuitry from damage. There is a 17-ms turn-on delay after VBUS 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.
