TheA1444 andA1445 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,
A1445 Features
* ▪ Low voltage operation: 1.8 to 4.2 V ▪ Externally controlled motor speed regulation ▪ Fast motor startup and braking function allows faster start-stop cycles ▪ Reverse voltage protection on the VDD and S¯¯L¯¯E¯¯E¯¯P pins ▪ Output short circuit and thermal shutdown protection ▪ Soft switching algori
