Question
STSPIN948: How should LSS1B/LSS2B and SENSEB be connected when bridge B is unused?
We are using the STSPIN948 in dual independent full-bridge mode, with only bridge A driving a motor.
Bridge B is unused, and OUT1B/OUT2B are left unconnected. EN/nFAULTB is held LOW to keep these outputs in the high-impedance state, as specified in Table 9 on page 13 of the STSPIN948 datasheet.
Could you please confirm whether LSS1B, LSS2B, and SENSEB should be connected directly to GND or left unconnected in this configuration? Please also advise on the recommended connections for REFB and TOFFB.
