8 Detailed Description
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
.

8.3 Feature Description
8.3.1 Over Voltage Protection on VBUS_CON up to 30 V DC
When the VBUS_CON voltage rises above VOVP, the internal nFET switch is turned OFF, removing power from the
system side. VBUS_CON can tolerate up to 30-V DC. The response to over voltage is very rapid, with the nFET
switch turning off in less than 100 ns. When the VBUS_CON voltage returns back to below VOVP – VHYS_OVP, the
nFET switch is turned ON again after an internal delay of tOVP_RECOV (tDELAY). This time delay ensures that the
VBUS_CON supply has stabilized before turning the switch back on. After tOVP_RECOV, the TPD1S514 Family device
turns on the nFET through a soft start. Once the OVP condition is cleared the nFET is turned completely ON.

Feature Description (continued)
8.3.2 Precision OVP (< ±1% Tolerance)
1% OVP trip threshold accuracy allows use of the entire input charging range while protecting sensitive system-
side components from over voltage conditions.
8.3.3 Low RON nFET Switch Supports Host and Charging Mode
The nFET switch has a total on resistance (RON) of 39 mΩ. This equates to a voltage drop of less than 140 mV
when charging at the maximum 3.5 A current level. Such low RON helps provide maximum potential to the
system as provided by an external charger or by the system when in Host Mode.
8.3.4 VBUS_POWER, TPD1S514-1, TPD1S514-2, TPD1S514-3
The VBUS_POWER pin provides up to 3 mA and 5 V for powering the system using VBUS_CON. VBUS_POWER follows
VBUS_CON after 3.5 V and up to the regulated 5 V. In the case where the system battery state cannot power the
system, voltage from an external charger can power the system. VBUS_POWER is supplied by an always on LDO
regulator supplied by VBUS_CON. The VBUS_POWER output voltage remains regulated to 5 V at up to 30-V DC on
VBUS_CON and during IEC 61000-4-5 surge events of up to 100 V.
8.3.5 VBUS_POWER, TPD1S514
The VBUS_POWER pin provides up to 3 mA and 6.48 V for powering the system using VBUS_CON. VBUS_POWER follows
VBUS_CON after 3.5 V and up to the regulated 6.48 V. 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. The VBUS_POWER output voltage remains regulated to 6.48 V at up
to 30-V DC on VBUS_CON and during IEC 61000-4-5 surge events of up to 100 V.
8.3.6 Powering the System When Battery is Discharged
There are two methods for powering the system under a dead battery condition. Case 1: The EN pin can be tied
to ground so that the nFET is always ON (when VUVLO < VBUS_CON < VOVP) and an external charger can power
VBUS. Case 2: If EN is controlled by a Power Management Unit (PMIC) or other logic, VBUS_POWER can be used to
power the PMIC. In Case 2, once the device is enabled, tDELAY + tSS, work together to meet the USB Inrush
Current compliance.
8.3.7 ±15 kV IEC 61000-4-2 Level 4 ESD Protection
The VBUS_CON pin can withstand ESD events up to ±15 kV Contact and Air-Gap. An ESD clamp diverts the
current to ground.
8.3.8 100 V IEC 61000-4-5 µs Surge Protection
The VBUS_CON pin can withstand surge events up to 100 V open circuit voltage (VPP), or 900 W. A Precision
Clamp diverts the current to ground and active circuitry switches OFF the nFET earlier than 100 ns before an
over voltage can get through to VBYS_SYS. The ultra-fast response time of the TPD1S514 Family holds the voltage
on VBUS_SYS to less than VOVP during surge events of up to 100 VPP
.
8.3.9 Startup and OVP Recovery Delay
Upon startup or recovering from an over voltage, the TPD1S514 Family of devices have a built in startup delay.
An internal oscillator controls a charge pump to control the delay. Once a manufactured pre-programmed time,
tDELAY, has elapsed, the charge pump is enabled which turns ON the nFET. A manufactured pre-programmed
soft start, tSS, is used when turning ON the nFET. Once the device is enabled, these start delays, tDELAY + tSS
,
work together to meet the USB Inrush Current compliance.
8.3.10 Thermal Shutdown
The TPD1S514 Family has an over-temperature protection circuit to protect against system faults or improper
use. The basic function of the thermal shutdown (TSD) circuit is to sense when the junction temperature has
exceeded the absolute maximum rating and shuts down the device until the junction temperature has cooled to a
safe level.

8.4 Device Functional Modes
8.4.1 Operation With VBUS_CON < 3.5 V (Minimum VBUS_CON
)
The TPD1S514 Family operates normally (nFET ON) with input voltages above 3.5 V. The maximum UVLO
voltage is 3.5 V and the device will operate at input voltages above 3.5 V. The typical UVLO voltage is 3.1 V and
the device may operate at input voltages above that point. The device may also operate at input voltages as low
as 2.7 V, the minimum UVLO. At input voltages between 0.6 V and 1.2 V, the state of output pins may not be
controlled internally.
8.4.2 Operation With VBUS_CON > VOVP
The TPD1S514 Family operates normally (nFET ON) with input voltages below VOVP_min. The typical OVP
voltage is VOVP_TYP and the device may operate at input voltages below that point. The device may also operate
at input voltages as high as VOVP_MAX
.

8.4.3 OTG Mode
The TPD1S514 Family of devices UVLO and OVP voltages are referenced to VBUS_CON voltage. In OTG mode,
VBUS_SYS is driving the VBUS_CON. Under this situation, initially VBUS_CON is powered through the body diode of the
nFET by VBUS_SYS. Once the UVLO threshold on VBUS_CON is met, the nFET turns ON. If there is a short to
ground on VBUS_CON the OTG supply is expected to limit the current.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The TPD1S514 Family of devices offer VBUS port protection implementing UVLO and OVP, with an LDO supplied
VBUS_POWER pin to regulate an output supply pin of 3 mA at 5 V (except for TPD1S514, which follows VBUS_CON up
to 6.48 V, after which it is regulated to that voltage). The VBUS_POWER pin can be used to power the system from
an external source on VBUS_CON in case the system’s battery state cannot power the system.
9.2 Typical Applications
9.2.1 TPD1S514-1 USB 2.0/3.0 Case 1: Always Enabled
The EN pin can be tied to ground so that the nFET is ON when VUVLO < VBUS_CON < VOVP and an external
charger can power VBUS. VBUS_POWER should be tied to ground with a 1-μF capacitor for LDO stability. USB Inrush
Current compliance tests will need to be handled by the rest of the system since the start delays tDELAY and tSS
implement only after the device changes from disabled to enabled, or after any UVLO or OVP event.

9.2.1.2 Detailed Design Procedure
To begin the design process the designer needs to know the VBUS voltage range.
9.2.1.2.1 VBUS Voltage Range
The UVLO trip-point is a maximum 3.5 V and the OVP trip-point is a minimum 5.9 V. This provides some
headroom for the USB 2.0 specified minimum 4.4 V (Low-power) or 4.75 V (Full-power) and 5.25 V maximum; or
the USB 3.0 specified minimum 4.45 V and 5.25 V maximum.
9.2.1.2.2 Discharged Battery
Connecting EN to ground sets the part active at all times. OVP and UVLO are always active, even when the
system battery is fully discharged. In the case of a discharged system battery, VBUS_SYS can be used to power
the system when a source with voltage between VUVLO and VOVP is attached to VBUS_CON
.

9.2.2 TPD1S514-1 USB 2.0/3.0 Case 2: PMIC Controlled EN
The TPD1S514 Family offers more flexibility to system designers to power up the system during a dead battery
condition. Refer to Figure 13, the VBUS_POWER pin supplies 4.95 V and 3 mA to power the PMIC in a dead battery
condition. Regardless of EN state, VBUS_POWER is available to the PMIC. Utilizing this power, the PMIC can
enable the TPD1S514 Family of devices when a valid VBUS_CON voltage is present.

•
VBUS voltage range
PMIC power requirement
9.2.2.2.1 VBUS Voltage Range
The UVLO trip-point is a maximum 3.5 V and the OVP trip-point is a minimum 5.9 V. This provides some

10 Power Supply Recommendations
The TPD1S514 Family is designed to receive power from a USB 3.0 (or lower) VBUS source. It can operate
normally (nFET ON) between a minimum 3.5 V and a maximum VOVP_MIN V. Thus, the power supply (with a
ripple of VRIPPLE) requirement for the TPD1S514 Family of devices to be able to switch the nFET ON is between
3.5 V + VRIPPLE and VOVP_MIN – VRIPPLE, where VOVP_MIN is:

11 Layout
11.1 Layout Guidelines
•
The optimum placement is as close to the connector as possible.
–
EMI during an ESD event can couple from the trace being struck to other nearby unprotected traces,
resulting in early system failures.
–
The PCB designer needs to minimize the possibility of EMI coupling by keeping any unprotected traces
away from the protected traces which are between the TVS and the connector.
•
•
Route the protected traces as straight as possible.
Eliminate any sharp corners on the protected traces between the TVS and the connector by using rounded
corners with the largest radii possible.
–
Electric fields tend to build up on corners, increasing EMI coupling.
11.2 Layout Example
VIA to Power Ground Plane
Power Ground
Power Ground
When designing layout for the TPD1S514 Family, note that VBUS_CON and VBUS_SYS pins allow extra wide traces for
good power delivery. In the example shown, these pins are routed with 50 mil (1.27 mm) wide traces. Place the
VBUS_CON, VBUS_SYS, and VBUS_POWER capacitors as close to the pins as possible. Use external and internal ground
planes and stitch them together with VIAs as close to the GND pins of TPD1S514 as possible. This allows for a low
impedance path to ground so that the device can properly dissipate any surge or ESD events.
