BQ79606A-Q1 Evaluation Module
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 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.
1.
Work Area Safety:
1. Keep work area clean and orderly.
2. Qualified observer(s) must be present any time circuits are energized.
3. 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.
4. All interface circuits, power supplies, evaluation modules, instruments, meters, scopes and other
related apparatus used in a development environment exceeding 50 V
RMS
or 75 VDC must be
electrically located within a protected Emergency Power Off (EPO) protected power strip.
5. Use a stable and non-conductive work surface.
6. Use adequately insulated clamps and wires to attach measurement probes and instruments. No
freehand testing whenever possible.
2.
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.
1. De-energize the TI HV EVM and all its inputs, outputs, and electrical loads before performing any
electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely
de-energized.
2. 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.
3. Once EVM readiness is complete, energize the EVM as intended.
