Pin Assignment
Three-phase logic truth table
S/S pin
N1 pin
The S/S pin does not have a built-in pull-up resistor, so an external pull-up resistor or equivalent is required to set the IC to
the stop state. If the S/S and PWMIN pins are not used, the unused pin input must be set to low-level voltage.
When the PWMIN pin is used for control, apply voltage between 4V and VREG to the EI + pin.
The HP output can be selected by the N1 pin setting from the N1 Hall input converted to a pulse output (one-Hall output)
or the three-phase output synthesized from the Hall inputs (three-Hall synthesized output).
With or without synchronous rectification when PWM is off can be specified by the SR pin.
