Note 1: Since the Sys.RES input is a higher priority input, all the logic are turned off when the Sys.RES goes Low,
which puts the motor in free run mode. Thus, the above table shows the motor status when the Sys.RES
signal is High.
Note 2:
: Don’t care.
5.
Phase Current Detection Circuit
The phase current detection at each phase of the coil is performed using the shunt resistor (Rf) connected
between the low-side output driver (IGBT or FET) and GND. The induced voltage at the shunt resistor is
amplified 3 times to be used as the internal signal. Since the current-voltage converted value is processed
based on 2.5 V, the maximum amplitude of shunt voltage must not exceed 0.5 V.
