... LB11691H Overview The LB11691H are three-phase bipolar PWM drive pre-driver ICs that allow the output circuits to be implemented using only n-channel FETs. These ICs can implement, at low cost, high-efficiency drive circuits in applications that use motors that require high drive currents. These ICs include a built-in Hall sensor signal F/V conversion circuit and can provide a voltage that is proportional to motor speed for use, for example, in speedometers for electric bicycles ...

... Description of LB11691H 1. Output drive circuit This IC is designed on the prerequisite that NchFET is used for both upper and lower outputs. To minimize power loss at the output, the direct PWM drive method is used. Output Tr is normally saturated at ON and the motor drive power is adjusted by changing the ON-duty of the output. PWM switching of the output is made on the lower output side to which UL, VL, and WL pins are connected ...
