TPD4S014DSQR

The TPD4S014DSQR is an ESD Protection Device for USB charger port protection including all lines and overvoltage protection on VBUS. It offers low capacitance transient voltage suppressor (TVS) electrostatic discharge (ESD) clamps for the D+, D- and standard capacitance for the ID pin. The device provides overvoltage protection (OVP) up to 28VDC. The overvoltage lockout feature ensures that if there is a fault condition at the VBUS line, it is able to isolate the VBUS line to protect the internal circuitry from damage. There is a 17ms turn-on delay after VBUS rises above the under voltage lockout (UVLO) threshold in order to let the voltage stabilize before turning the nFET on. This function acts as a deglitch and prevents unnecessary switching if there is any ringing on the line during connection.
