Product Summary

The TPD4S014DSQR is a single-chip solution for USB charger port protection. This device offers low capacitance TVS type ESD clamps for the D+, D- and standard Capacitance for the ID pin. On the VBUS pin, this device can handle over-voltage protection up to 28V. The over voltage lock-out feature ensures that if there is a fault condition at the VBUS line, the TPD4S014DSQR is able to isolate the VBUS line and protects the internal circuitry from damage. Similarly, the under voltage lock out feature ensures that there is no power drain from the internal VCC plane to external VBUS side in case there is short to GND. The applications of the TPD4S014DSQR include Cell Phones, eBook, Portable Media Players, Digital Camera.
