General TI High Voltage Evaluation User Safety Guidelines
Always follow TI's set-up and application instructions, including use of all interface components within their
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
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions may 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 should immediately stop from further
use of the HV EVM.
Work Area Safety:
– Maintain a clean and orderly work area .
– Qualified observer(s) must be present anytime circuits are energized.
– Effective barriers and signage must be present in the area where the TI HV EVM and its interface
electronics are energized, indicating operation of accessible high voltages may 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 V
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, it is always a good engineering practice to assume that the entire
EVM may have fully accessible and active high voltages.
– De-energize the TI HV EVM and all its 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.

    Using the LMG3410-HB-EVM Half-Bridge and LMG34XX- BB-EVM Breakout Board EVM The LMG3410-HB-EVM features two LMG3410 600V/12A GaN power transistors with integrated drivers that are configured in a half bridge with all the required bias circuit and logic/power level shifting. Essential power stage and gate driving high frequency current loops are fully enclosed on the board to minimize parasitic inductances, reducing voltage overshoots and improving performance.

    Trademarks All trademarks are the property of their respective owners. Description The LMG3410-HB-EVM operates as a daughter card as part of a larger custom designed system or with the LMG34XX-BB-EVM breakout motherboard. LMG3410-HB-EVM The LMG3410-HB-EVM configures two LMG3410 GaN FETs in a half bridge. All the bias and level shifting components are included, allowing low side referenced signals to control both FETs.

    1.1.1 FAULT The FAULT pin of LMG3410-HB-EVM is active low when an under voltage lockout on an auxiliary voltage rail, over temperature or overcurrent even occurs on the LMG3410. The FAULT signal for both LMG3410 devices are level shifted to AGND, where they are logic AND connected to the FAULT pin.
  • Page 6 1.1.3 Bootstrap Mode The LMG3410-HB-EVM card can be modified to operate in bootstrap mode, where the 12V bias voltage is used to power both LMG3410 devices. This can be achieved by removing U3, U4 and R2, and placing a 20 Ω resistor on R1, a 0 Ω resistor on R18 and a 600V SOD-123 diode on D1, such as Micro Commercial Components UFM15PL-TP.
  • Page 7 The FAULT LED will still illuminate when either LMG3410 has an active fault, regardless of the position of FAULT Protect jumper. Typical Applications The LMG3410-HB-EVM is designed for use in AC/DC, DC/DC and DC/AC applications • Totem-Pole PFC converters •...
