A1444 And A1445 Low-Voltage Full-Bridge Brushless DC Motor Driver With Hall Commutation, Externally Controlled Speed Regulation, Soft Switching, And Reverse Battery, Short Circuit, And Thermal Shutdown Protection

The A1444 and A1445 are full-bridge Motor Drivers designed to drive low-voltage brushless DC (BLDC) motors in applications that require rotor speed control and fast rotor start-stop cycles. A high density CMOS semiconductor process allows the integration of a Hall element, a full-bridge output driver, and PWM speed control Logic into one monolithic IC. Commutation of the motor is achieved by use of a single Hall element Sensor to detect the rotational position of an alternating-pole ring magnet. Low-voltage design techniques have been employed to achieve full device functionality down to a VDD of 1.8 V. The voltage applied to the PDC pin is used to externally control the maximum speed of the motor by adjusting the PWM duty cycle of the output driver.
