HV7100 Overview
The HV7100 is an integrated PWM speed controller for driving 24 and 48VDC fans.
HV7100 Key Features
- High-side drive allows use of tachs -- Direct interface to host controller -- Noise-immune linear speed control -- 4-bit
HV7100 Applications
- 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 ponent sizes
