AH9281规格书详情
描述 Description
The AH9281/82 is a one-chip solution for driving
two-coil brushless DC motors and fans.
Based on the advanced CDMOS process, the IC
contains a Hall-effect sensor, dynamic offset
correction and powerful output drivers with 1200mA
peak output current capability.
Specially designed for driving large fans, the device
is optimized for low start-up voltage. Frequency
Generator or Rotation Detection is available. The
open drain output makes easier the connectivity with
any external interface such as hardware monitoring or
Super I/O IC.
