TPD1S514x
SLVSCF6F – APRIL 2014 – REVISED MAY 2019
TPD1S514x Family USB Charger Overvoltage, Surge and ESD Protection for VBUS PIN
1 Features
1 Overvoltage Protection at VBUS_CON
up to 30-V DC
• Precision OVP ( < ± 1% Tolerance)
• Low RON nFET Switch Supports Host and
Charging Mode
• Dedicated VBUS_POWER Pin Offers Flexible Power
up Options Under Dead Battery Condition
• Transient Protection for VBUS Line:
– IEC 61000-4-2 Contact Discharge ±15 kV
– IEC 61000-4-2 Air Gap Discharge ±15 kV
– IEC 61000-4-5 Open Circuit Voltage 100 V
– Precision Clamp Circuit Limits the VBUS_SYS
Voltage < VOVP
• USB Inrush Current Compliant
• Thermal Shutdown (TSD) Feature
2 Applications
• Cell Phones
• Tablets
• eBook
• Portable Media Players
• 5-V, 9-V, and 12-V Power Rails
3 Description
The TPD1S514 Family consists of single-chip
protection solutions for 5-V, 9-V or 12-V USB VBUS
lines, or other power buses. The bidirectional nFET
switch ensures safe current flow in both charging and
host mode while protecting the internal system
circuits from any over voltage condition at the
VBUS_CON pin. On the VBUS_CON pin, this device can
handle over voltage protection up to 30-V DC. After
the EN pin toggles low, any device in the TPD1S514
Family waits 20 ms before turning ON the nFET
through a soft start delay.
Typical application interfaces for the TPD1S514
Family are VBUS lines in USB connectors typically
found in cell phones, tablets, eBooks, and portable
media players. The TPD1S514 Family can also be
applied to any system using an interface for a 5-V, 9-
V, or 12-V power rail.
