ADM1033 Rev. 0 is a thermal monitor and fan speed controller with 1 local and 1 remote temperature channel, automatic series resistance cancellation, fast measurement speed, programmable over-temperature limits and fault queue, as well as features such as fan speed control and temperature-to-fan-speed lookup table.
The ADM1033 is a device designed to monitor local and remote temperatures and control the speed of a cooling fan. It features a look-up table for temperature-to-fan-speed control, supporting both discrete and linear modes. The device communicates via a 2-wire SMBus 2.0 interface and includes an 8-level LOCATION input for SMBus version selection.
