Texas Instruments TPD4S014 Single-Chip Charger Port Protection Solution

Texas Instruments TPD4S014 Single-Chip
Charger Port Protection Solution

Texas Instruments TPD4S014 single-chip solution for USB charger port protection offers low capacitance TVS type ESD clamps for the D+, D-, and standard capacitance for the ID pin. On the VBUS pin, the TI TPD4S014 can handle over-voltage protection up to 28V. TI TPD4S014 charger port protection solution supports >2A charging current and provides a low capacitance TVS ESD clamp for USB 2.0 high-speed data rate. This TI device features 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. The TPD4S014 is ideal for use in cell phones, eBook applications, digital cameras, and portable media players.
