BD67891MUV
Description
BD67891MUV is a level-shifter that converts control logic signals from the ASIC to signals for direct driving of the external FET's gate as well as Hall and FG output signals from the motor side for input signals to the ASIC during 3-phase DC brushless motor driving. Additional features include a current limit function that enables setting of the OFF time by external CR, a thermal shutdown circuit and under voltage lock out circuit for high reliability operation. A power save function is also integrated that reduces circuit current during standby, contributing to greater overall energy savings.
