BD67173NUX

General Description

Key Specifications

BD67173NUX is a three-phase sensorless fan motor

driver used to cool off notebook PCs. It is controlled by a

variable speed provided through the PWM input signal.

Its feature is sensorless drive which doesn’t require a

hall device as a location detection sensor and motor

downsizing can be achieved by limiting the number of

external components as much as possible.



Operating Supply Voltage Range: 2.2V to 5.5V

Operating Temperature Range: -25°C to +95°C

Package(s)

VSON010X3030

W(Typ) x D(Typ) x H(Max)

3.00mm x 3.00mm x 0.60mm

Furthermore, introducing a direct PWM soft switched

driving mechanism achieves silent operations and low

vibrations.

Features

 Speed controllable by PWM input signal

 Sensorless drive

 Soft switched drive Quick start

 Power save function

 Internal RNF resistance

 Quick start function
