RAJ306010 RSSK(RTK0EML2C0S01020BJ)
4.10 HALL IC input terminal
CN_HALL connector and through-hole for checking (CN1) are provided for Hall IC signal input.
When the motor has a thermistor terminal or a COMMON terminal, terminal No.1 of CN_HALL can be used to
select either input by setting JP3. Pins No.3-No.5 are used to input Hall IC signals. The input Hall signals are
input to the RAJ306010 via a pull-up with 5V and an RC filter. Please refer to the circuit diagram for the filter
constants. In case of sensor-less control (when input from Hall IC is not used), BEMF output can be output from
terminal No.3. when BEMF output is used, if peripheral circuit is attached, it will interfere with input to ANI7 (IC
internal connection), so filter adjustment is required. When stopping BEMF output by software setting, it is not
necessary to set the filter constant. For details, please refer to the RAJ306000 Series User's Manual Hardware
Edition (R18UZ0066EJ).
Power supply (VDD:5V) for Hall IC can be supplied from pin No.6.
