... Accordingly, the output is not recovered unless the voltage rises by about 0.5V above the activation voltage output For the HP output, the composite signal of three phases of Hall element signal is output. This is an open collector output. This can be used for the motor rotation detection signal, etc. LB11920 No.7229-9/10 ...
