DC motor drivers for Fan Modules

Small DC motors are used in various office equipments (copiers, printer and scanners), home appliances (video/CD/DVD players, toys), PCs and handheld devices.

The drive and control electronics contribute to improve the DC motors' efficiency and reliability within their applications. From simple bridges to advanced controller ICs, their role is to adjust the motor speed, torque, direction of rotation, acceleration and braking functions, in open loop or servo systems, hence optimizing the power consumption. Also they can provide important protection features that improve the security and lifetime of the end-product.

The ASMTD6101/2A is Advanced Silicon's first IC addressing the need of a very widespread type of brushless DC motor, the cooling fan for electronic devices.
