Texas Instrument’s TPD1S514-3 evaluation module helps designers evaluate the operation and performance of the TPD1S514-3 device. The TPD1S514-3 is a single-chip solution for a USB connector’s VBUS line protection. The bi-directional nFET switch ensures safe current flow in both charging and host mode while protecting the internal system circuits from any over-voltage conditions at the VBUS_CON pin. On the VBUS_CON pin, this device can handle over-voltage protection up to 30V. After the EN pin toggles low, the TPD1S514-3 waits 21 ms before turning ON the nFET through a startup delay. VBUS_POWER pin indicates the nFET is completely turned ON.
