Note: 1. The “H” state for FR means a voltage of 2.75 V or higher, and the “L”
state means a voltage of 2.25 V or lower. (When VCC = 5 V.)
2. For the Hall inputs, the input “H” state means the state in which the
(+) input for that phase is at least 0.01 V higher than the (–) input for
that phase. Similarly, the “L” state means the state in which the (+)
input for that phase is at least 0.01 V lower than the (–) input for that
phase.
3. Since this drive technique is a 180° power application technique, the
phase that is neither the source phase nor the sink phase does not
turn completely off.
