8.1 Overview

The TPD1S514 Family provides single-chip ESD, surge, and over voltage protection solutions for portable USB Charging and Host interfaces. Each device offers over voltage protection at the VBUS_CON pin up to 30-V DC. The TPD1S514 Family offers an ESD and Precision Clamp for the VBUS_CON pin, thus eliminating the need for external TVS clamp circuits in the application.

Each device has an internal oscillator and charge pump which controls turning ON the internal nFET switch. The internal oscillator controls the timers which enable the charge pump. If VBUS_CON is less than VOVP, the internal charge pump is enabled. After a 20 ms internal delay, the charge-pump starts-up, and turns ON the internal nFET switch through a soft start. If at any time VBUS_CON rises above VOVP, the nFET switch is turned OFF within 100 ns.

The TPD1S514 Family of devices also have a VBUS_POWER pin which follows VBUS_CON up to 4.9 V at 3 mA (except for TPD1S514, which follows VBUS_CON up to 6.48 V, after which it is regulated to that voltage) to power the system from VBUS_CON. In the case where the system battery state cannot power the system, voltage from an external charger can be provided to power the system. VBUS_POWER is supplied by an always on LDO regulator supplied by VBUS_CON. VBUS_POWER output voltage remains regulated to 4.9 V (except for TPD1S514, which follows VBUS_CON up to 6.48 V, after which it is regulated to that voltage) at up to 30-V DC on VBUS_CON and during IEC 61000-4-5 surge events of up to 100 V open circuit voltage on VBUS_CON.
