AN44168A and AN44169A from Panasonic are high efficiency single-phase motor driver ICs with built-in soft switching function for low noise operation. The soft switching period is automatically adjusted based on the motor current. This eliminates the need for individual adjustment of the soft switching period based on the motor's specifications.
These driver ICs for 1-phase brushless motors have been designed for use with industrial products like base stations or severs, OA equipment, beauty home appliances and white goods.
These drivers have real time auto phase correction and detected motor current and keeps good rotation efficiency for reducing power consumption.
- Real time auto phase correction
- Build in soft switching function and protection reduces the number of external components
