EVALUATION BOARD DESCRIPTION
The
is a full-featured evaluation board
designed to allow the user to easily evaluate all features of the
resolver-to-digital converters.
To evaluate the
(see Table 7). The evaluation board can be controlled via the
SDP connector (J2). The SDP board allows the evaluation board
to be controlled through the USB port of a PC using the
SDP connector (J2). The SDP board allows the evaluation board
to be controlled through the USB port of a PC using the
software.
On-board components include: the
precision rail-to-rail
4-channel voltage monitor and sequencer, the
high accuracy 200 mA low dropout linear regulator,
the
high-
side power switch, the
voltage supervisory device, and
the
bidirectional logic level translators.
The evaluation board features a high current driver with user
configurable gain that amplifies and biases the excitation
outputs, which allows the evaluation board to be connected
directly to a resolver. This high current driver circuit is
described in detail in Circuit Note
