MAX6643
Overview
The MAX6643/MAX6644/MAX6645 monitor temperature and automatically adjust fan speed to ensure optimum cooling while minimizing acoustic noise from the fan. Each device measures two temperature locations.
- Simple, Automatic Fan-Speed Control
- Internal and External Temperature Sensing
- Detect Fan Failure Through Locked-Rotor Output, Tachometer Output, or Fan-Supply Current Sensing
- Multiple, 1.6% Output Duty-Cycle Steps for Low Audibility of Fan-Speed C
