DESCRIPTION
The IC controls the voltage across a DC fan motor as a function of the voltage applied to the control input “SOLL”. The IC delivers the gate voltage for one or two (parallel) external power-FETs, which linearly drive the load current of the motor. The drain currents of the two external power-FETs are matched by measuring the voltages across each individual shunt resistor.

FEATURES
► Supply voltage range VS 7.2V to 17.5V
► Overvoltage shut down
► Low standby current (power down mode)
► Limitation of power dissipation by voltage dependent current limitation
► Externally adjustable minimum current
► Externally adjustable over temperature protection featuring load current reduction
► Control of current distribution in 2 parallel power-FETs
► Turn on the power-FETs during load-dump
► – 40°C to + 125°C operating temperature
► SO16w package

APPLICATION
► Fan regulation
