Product details

Description

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.

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 algorithm for reduced audible switching noise and EMI interference.
Unidirectional operating mode results in motor rotation in only one direction.
Chopper stabilization red.
