DESCRIPTION

The TPD4S014 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 TPD4S014 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. There is a 16ms turn-on delay after VBUS crosses

the under voltage lockout threshold, in order to let the voltage stabilize before closing the switch. This function

acts as a deglitch and prevents unnecessary switching if there is any ringing on the line during connection.
