General Description
The HV7100 is an integrated PWM speed controller for driving
24 and 48VDC fans. The features and benefits provided by the
HV7100 make driving fans simple and low cost. The HV7100
drives a high side external P-channel FET, allowing the use of
fans having a ground-based tachometer signal. It has a wide input
voltage range of +16 to +90V, ideal for +24 or +48V systems. No
low voltage supply is needed.
A 4-bit digital control input provides direct interfacing with a micro
controller or system processor to control the fan speed. It can
also be used as a stand-alone fan controller, via a thermistor
connection to the Linear Control pin.
The HV7100 has a wide PWM frequency range. When driving
fans directly with a PWM supply voltage, frequency may be set
low, around 50 - 120Hz. When used to drive fans requiring a DC
supply, an LC filter may be employed. In this case, PWM frequency
may be as high as 100kHz, reducing component sizes in the filter.
The HV7100 is an ideal device to incorporate in fan trays and fan
control modules, as it reduces circuit complexity and minimizes
parts count and overall cost for thermal management.
