ADM1033: Thermal Monitor and Fan Speed Controller
The ADM1033 is a one channel remote- and local-temperature sensor and fan controller. The remote channel monitors the temperature of the remote thermal diode, which may be discrete 2N3904/6s or may be located on a microprocessor die. The device also monitors its own ambient temperature.
Features- 1 Local and 1 Remote Temperature Channels
- ±1.5°C Accuracy on Local and Remote Channels
- Automatic Series Resistance Cancellation on Remote Temperature Channels, > 100 Ω
- Fast (up to 64 measurements a second)
- SMBus 2.0, 1.1 and 1.0 Compliant
- SMBus Address Input / Location Input to UDID
- Programmable Over / Under Temperature Limits
- Programmable Fault Queue
- SMBus / ALERT Output
- Failsafe Over-temperature Comparator Output
- RPM Fan Speed Control
- Lookup Table for Temperature to Fan Speed Control
