1.5 General TI High Voltage Evaluation User Safety Guidelines
WARNING
Always follow TI’s set-up and application instructions, including use of all interface components within the
recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure
your personal safety and the safety of those working around you. Contact TI’s Product Information Center http://
support/ti./com for further information.
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions can result in personal injury, property damage, or death due
to electrical shock and/or burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed
circuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified
professional users having training, expertise, and knowledge of electrical safety risks in development and
application of high-voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas
Instruments. If you are not suitably qualified, you must immediately stop from further use of the HV EVM.
•Work Area Safety:
– Maintain a clean and orderly work area .
– Qualified observers must be present anytime circuits are energized.
– Effective barriers and signage must be present in the area where the TI HV EVM and the interface
electronics are energized, indicating operation of accessible high voltages can be present, for the purpose
of protecting inadvertent access.
– All interface circuits, power supplies, evaluation modules, instruments, meters, scopes and other related
apparatus used in a development environment exceeding 50 VRMS/75 VDC must be electrically located
within a protected Emergency Power Off (EPO) protected power strip.
– Use a stable and non-conductive work surface.
– Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand
testing whenever possible.
•Electrical Safety:
As a precautionary measure, a good engineering practice is to assume that the entire EVM can have fully
accessible and active high voltages.
– De-energize the TI HV EVM and all the inputs, outputs, and electrical loads before performing any
electrical or other diagnostic measurements. Confirm that TI HV EVM power has been safely de-
energized.
– With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring,
measurement equipment hook-ups and other application needs, while still assuming the EVM circuit and
measuring instruments are electrically live.
– When EVM readiness is complete, energize the EVM as intended.
WARNING
WARNING: While the EVM is energized, never touch the EVM or the electrical circuits as
the EVM or electrical circuits can be at high voltages capable of causing electrical shock
hazard.
•Personal Safety:
– Wear personal protective equipment, for example, latex gloves and/or safety glasses with side shields or
protect EVM in an adequate lucent plastic box with interlocks from accidental touch.
•Limitation for Safe Use:
– EVMs are not to be used as all or part of a production unit.

3.2 Performance Data and Results
Test Procedure
•Power Up
1. Before proceeding make sure the EVM and all equipment is setup as described in section Equipment
Configurations and Equipment Setup.
2. Turn on the 5 V and 24 V power supply. Probing VDDB(TP16)-VSSB(TP9) measures 20 V. Probing
VCC1(TP1)-GND(TP6) measures 5 V.
3. Turn on both channels of the function generator.
4. Use any probe of choice to verify that there is a 5 KHz, 5 V, pulse on INA and INB each with respect to
GND.
5. Probing VGA-VSSA and VGB-VSSB shows a PWM output signal from the gate driver going up to +16V
when HIGH and -3V when LOW as shown in Figure 3-2.

Deadtime Configuration
The UCC21551 has 3 dead time modes that are selectable with the UCC21551CQEVM. Those modes are
Interlock, Programmable, and Overlap.
•Interlock Mode: Interlock mode sets a minimum delay of approximately 5 ns between gate driver outputs to
prevent the channels from overlapping. This mode is initiated when the dead time pin is grounded (Shunting
J5 to DT-GND). The dead time is defined as the delay between 90% of the falling edge of the first output and
10% of the rising edge of the second output. Timing is illustrated in Figure 3-3. See Figure 3-4for an example
of Interlock mode.

•Programmable Mode: Programmable dead time mode is activated when the dead time pin is connected
to a resistor between 1.7K-100K Ohms to ground. To activate this mode on the EVM, leave jumper J5
unconnected. To adjust the deadtime, use the switches on SDT_DT1. By default, switch the switches to the
left. To program the dead time, move the switch to the right. The available resistors allow for various dead
time settings. Additional values can be created by toggling multiple switches at the same time, which has the
effect of paralleling the resistors. Figure 3-5 is an example output waveform with 5 kΩ resistance.
Figure 3-5. Programmable Mode: 5 kΩ RDT Resistor Selection
•Overlap Mode: Overlap mode disables the deadtime circuitry to allow the outputs to overlap. To select this
mode, shunt jumper J5 to VCC-DT. An example of overlap mode is depicted in Figure 3-6.

Single Input PWM
Single input PWM allows the user to control channel A and B with a single PWM signal. On the EVM, this is
accomplished with a BJT inverter circuit that takes the incoming channel A signal inverts and forwards to the
input pin of channel B. To enable this mode, shunt jumper 23. Note that in this mode, there is an unavoidable
intrinsic dead time of 1us imposed by the BJT switching delay. This only occurs between the falling edge of
VGA and the rising edge of VGB. If the deadtime circuit of the UCC21551 is enabled, then the interlock and
programmable deadtime modes only affects the rising edge of VGA and the falling edge of VGB. This is because
the 1us deadtime caused by the BJT is happening in parallel with the gate driver deadtime instead of adding. In
Figure 3-7 and Figure 3-8, the driver is in interlock mode and both channels are switching at the same frequency.
As the frequency increases, the output pulses eventually become smaller than the 1us delay. Figure 3-8 is
depicting switching at 200 kHz, at which about half of INB’s signal is lost.

Active Clamp
The Active clamp is a protection circuit added to channel B of the UCC21551CQEVM. This circuit helps keep the
gate low when the driver is not powered or if there is an unintended voltage rise coupling to VGB. If there is a
rise in the voltage on VGB greater than the voltage on OUTB, then the PNP BJT turns on and provides a path
for current to flow to ground instead of into the FET gate, which can turn the FET on. The active clamp clamps
voltage transients on VGB to approximately 1.2V. This is shown in Figure 3-9.
Figure 3-9. Active Clamp Clamping an Unintended Rise on VGB
Onboard Adjustable Bias Supply (UCC14240)
The UCC14240 is a 1.5W isolated adjustable bias supply configured to supply 20 V to the low side (channel B)
of the gate driver. The user can change this output voltage to accommodate different versions of UCC2155XX
drivers by changing resistor R28. For more information on how to adjust the output voltages, refer to the
UCC14240-Q1 Component Calculator and the application note UCC14240-Q1 Simplifies HEV, EV, Bias Supply
Design for Isolated Gate Drivers.
Negative Bias Supply Generation
The UCC21551CQEVM is equipped with a zener diode circuit on both gate driver output channels. This takes
the 20 V VDD supply and splits into +16/-3V. Applying a negative bias to the gate of MOSFET mitigates the
system from having unintentional turn on of the MOSFET caused by current flowing through the miller capacitor
during high dv/dt switching. The negative pulldown circuit needs multiple cycles to reach steady state. Not all
tests, such as a double pulse test, feature a negative voltage on the gate when performed.
High Voltage Double Pulse Test
This UCC21551CQEVM-079 was designed to work with voltages of up to 800 V. A low side double pulse test
was performed to test the high voltage capability of the EVM. This test consisted of a Wolfspeed XM3 evaluation
board which includes a SiC FET module and DC bus capacitor. The inductor is connected across the high side
FET so the body diode can free-wheel the inductor current while the low side FET switches.
