HV7100  
24/48V Fan Driver/Controller  
With High-Side Drive  
Features  
General Description  
High-side drive allows use of tachs  
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.  
Direct interface to host controller  
Noise-immune linear speed control  
4-bit digital speed control  
Operates from single +24/+48V supply  
Programmable PWM frequency  
Undervoltage lockout  
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.  
Applications  
24/48V chassis cooling tray  
Servers  
SAN equipment  
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.  
Cellular and fix wireless systems  
24/48V PBX system  
Base stations  
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.
