As seen from the image above, the EVM has multiple power rails that are derived from input power sources. The
12 V supply voltage is fed into a LMR43610 buck converter to derive the 3.3V rail for the high-side switch. This
buck converter is used for the low IQ functionality, so that the low-power mode of the high-side switch can be
measured through the EVM. A TLV767 LDO is used to derive the 3.3V micocontroller supply from the 5 V USB
connection through the PC.
Note that this board is intended to evaluate the standard functionality of the device. The board is not designed
to withstand automotive transients events such as hard short-to-ground events, reverse battery events, and
ISO 16750-2 load dumps. If short-to-ground is to be performed on the EVM, then TI recommends to add a
capacitance on the order of 220 µF so that the device can withstand the short-to-ground event. Additionally, as
the EVM is built for evaluation with ample test points, the EVM is not optimized for EMC testing and performance
including emissions, RF, and transient immunity tests.
