产品说明

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 Over Voltage Protection (OVP) up to 28 V DC. The over voltage 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 Under Voltage 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.
